Dylan, Rommie, Tyr, and Harper are returning in the Maru from signing a non-aggression pact with the Kalderans when they are attacked by Ogami pirates, and the slipstream drive is damaged. They receive a message from a woman that seems to be a distress call, but the exact meaning of the message is unclear. Suddenly, a massive ship arrives. The ship destroys several Ogami ships by using the exhaust from its engines as a weapon, and takes the Maru into its hangar.

On the Andromeda, Beka and Trance are trying to determine what has happened to the Maru. They find evidence of the battle, but no clear evidence that the Maru was destroyed.

Tyr, Rommie, and Harper are arming themselves from the Maru's weapons locker, but Dylan objects, on the basis that they were saved by the crew of this ship. He asks Rommie what she can tell them about the ship, and she speculates that it may be a human design, perhaps even from Earth.

The ship contacts the Maru on the comms system, saying that they do not want trouble. Dylan agrees to let the contact team board. It consists of humans in uniform, identifying them as the Bellerophon Deep Space Expedition, and is led by a woman named Nadia, who was the woman in the message. Harper is amazed at the mention of the Bellerophon, saying that no one has heard of that ship in centuries.

Dylan and the others follow Nadia onto the ship. He says that they received their distress signal, but Nadia denies sending any signals. Dylan asks to see the ship's captain. Nadia says that this is not possible, but is interrupted by the captain on the ship's PA system, ordering her to bring Dylan to the bridge, and she complies. The Ogami are still attacking.

The Ogami board the ship, and Dylan offers to help fight them. Captain Metis, declines, saying that Dylan is a guest on his ship, so he should stay out of the way while the crew fights. The Bellerophon's crew, armed with conventional slug-throwing firearms, fight the Ogami boarders, some of which are armed with more "modern" weapons, and some of which carry hand-to-hand weapons. Despite what Metis said, Dylan joins the fight, saving Metis from an Ogami. Metis is grateful.

Rommie and Tyr are also fighting the Ogami, and Metis is impressed by Rommie's combat capabilities.

Harper hacks into the Ogami ships' controls, and causes them to be destroyed.

Dylan, Metis, and the others kill the rest of the Ogami on the Bellerophon.

The Bellerophon is low on fuel, so Metis orders the crew to take them to the corona of a nearby sun to re-fuel. He is grateful for Dylan's help, and offers him anything he can do to help him. Dylan asks for help repairing the Maru, and Metis agrees.

As Nadia is helping clean up after the battle, she mutters about their losses, and wonders how much more they can take.

Beka and Trance continue to look for the Maru. Andromeda detects an ion trail leaving the system, which she says may have been left by the Maru. Beka notes that there is a danger that if they leave the system, they might not be able to find a slip point between systems, but she follows the trail anyway.

Kemp, a member of the Bellerophon's crew, is helping Harper on the Maru, but he does not even know what a slipstream drive is. Harper explains slipstream travel to him, and compares it to the Bellerophon's method of travel, which involves time dilation from travelling close to the speed of light. The two of them reminisce about Earth, but Harper avoids talking about what has happened to Earth recently.

Dylan tells Metis about being trapped in the black hole, and the state of civilization. Metis is impressed by Dylan's efforts to restore the Commonwealth. Metis tells Dylan about his journey, and the wonders he has seen, but also the strain of not seeing anyone but his own crew for long periods of time. Metis compares the two of them, and how they are both driven by their missions. Dylan agrees, noting that he has to get back to the Andromeda to continue his mission.

Harper determines that the slipstream drive is beyond repair, but they are too far out from civilization to get a message to anyone in a reasonable amount of time. Metis offers to take them to the nearest civilized planet, but while that would only take three months of subjective time, it would be 57 years of real time, which Dylan deems unacceptable.

Metis is explaining the operation of the Bellerophon to Rommie. He seems impressed, and a little taken with her, and she with him. Rommie tells him that she is not unique, there are other androids and avatars. Metis insists that the others are not like her, she is a unique individual. Rommie is pleased by this, but warns Metis that Dylan will not accept being taken away from his mission, so Metis would be well-advised to not get in his way. Metis says that he wants to help, but his crew, ship, and mission must come first.

Andromeda is searching for the Maru in interstellar space. Andromeda warns Beka that it is harder to find a slip portal, but by fine-tuning the systems, they might be able to force one open. Beka and Trance resolve to try this, although they acknowledge that it would be easier if Harper were on board.

Harper and Kemp are still working on the Maru. Kemp, noting that Harper was from Boston, tells how he spent his last night on Earth in Boston. Harper finally tells him what has happened on Earth since then – the wars, the Magog invasions, and finally the rule of the Drago-Kazov. Kemp is shocked, and insists that they have to go and save Earth.

Metis and Nadia are arguing. Nadia insists that the mission is over, because there is no home to go back to. Metis will not listen, and insists that she chose to follow him.

Metis offers to drop Dylan on a planet in the system that is habitable, but inhospitable, in the hopes that someone will pick him up before the 57 years pass. He says that he actually wants Dylan to stay with him on the ship.

Dylan and his crew discuss their options. Dylan is inclined to take the offer to stay on the planet. Harper feels that the ship is safer and more comfortable. Rommie is interested in seeing the kinds of things that Metis has described, and enjoys the fact that, on this ship, she is unique. Tyr insists that Dylan only has one choice – staying on the ship means abandoning his mission, and Dylan has not shied away from risk and danger before, so the planet is his only option.

Nadia interrupts the discussion. She tells Dylan that she think that they do have the means to fix the Maru on the Bellerophon, but Metis is keeping it from Dylan. She intends to mutiny against Metis, and, if Dylan will help her, she will give him what he needs.

Beka and Trance are attempting to re-route the anti-matter circuits to force open a slip portal, but they are having difficulty. They refer to Harper's help files.

Nadia explains to Dylan that the initial message he received, that he took for a distress call, was a message she sent to Kemp on internal communications. She claims that Metis is obsessed with his mission, and the crew are effectively his prisoners. Dylan says that he could take information about the mutiny to Metis, but Nadia reminds him that they can give him the technology to fix his ship, while Metis will not.

Rommie goes to Metis' quarters, and distracts him with a kiss while she steals an identification card from him.

Tyr disables the motion detection system while Rommie uses the ID card and mimics Metis' voice to open a secure door. She finds a damaged, but intact, slipfighter. Dylan is upset about being lied to, and realizes that Metis was making every effort to prevent his crew from considering leaving.

Harper says that he would be able to fix the Maru using the slipfighter's drive, but this would require assisting the mutiny. Dylan goes to talk to Metis, and tells him that the mutiny is already underway. Metis asks him if he is a part of the mutiny, but Dylan counters by asking him why he did not tell them about the slipfighter. Metis offers to give him the slipfighter if he will help put down the mutiny.

Kemp, with the assitance of other mutineers, takes Harper hostage on the Maru.

Nadia enters the bridge, with armed troops. Metis uses the ship's acceleration to knock them down. Dylan helps Metis disarm them, but prevents him from killing them outright. He convinces Metis to let her and the other mutineers leave the ship with him, saying that Metis can continue his mission with a smaller crew.

Metis and Rommie say their farewells. Metis invites Rommie to stay. She says that while she does feel unique on the Bellerophon, she must stay with Dylan. Rommie says that android bodies do, however, last a long time, and she may still be around when Metis completes his mission. They kiss goodbye.

When the Maru leaves the Bellerophon, Nadia and Kemp are on board. Dylan says that he will take them wherever they want to go, but they are welcome to stay. The Andromeda arrives, and picks up the Maru.

Dylan and Rommie meet on the Obs Deck. Dylan says that he is a little jealous of Metis, for the things he has seen, and he has gained a new respect for the explorers. Dylan and Rommie promise each other that when their current mission, to restore civilization, is complete, they will do some exploring of their own.
