The crew of a derelict ship awakens from stasis with no memories of who they are or how they got onboard. Their search for answers only leads to more questions, a mysterious weapons cache, and the awakening of the vessel’s security system, an android bent on their destruction. Much of the vessel's data has been wiped, but they manage to retrieve information pertaining to the ship's original destination - an independent mining colony with some shocking revelations.

More shipboard mysteries abound as the crew struggles to come to terms with recent revelations. A mysterious locked door, an unfathomable puzzle box, and an exploration of the ship’s maze-like vent systems ratchet the tension as a decision is reached on the desperate miners. Complications arise in the form of a corporate ship, a Ferrous Corp Destroyer, whose surprise arrival violently disrupts the crew’s best laid plans. Meanwhile, questions persist: Who wiped their memories? And why?

Five’s exploration of the ship’s maze-like vent system yields a shocking discovery, but before the crew can investigate, the ship drops out of FTL. What at first appears to be a mechanical issue soon becomes a suspected case of sabotage. Amid the burgeoning paranoia, secret alliances are made as the bad news gets even worse. The crippled vessel is taking on radiation from a nearby star that has gone supernova - and the only way to fix the problem is for someone to topside and execute a dangerous spacewalk repair.

The crew visits a space station to take on supplies, effect repairs, and get some much-needed R&R, but the greatly anticipated stopover take a series of unexpected turns. Six’s visit to a local clinic wins him some unwanted attention, One and Three’s attempts to sell the weapons in their cargo hold lands them at a dangerous disadvantage, Two and Five learn that some games of chance come with surprising risks, while Four makes a stunning discovery about his past.

The crew is hired by their handler, Tabor Calchek (David Hewlett), to salvage an abandoned freighter, The Far Horizon. What at first appears to be a straightforward reclaim op turns into a fight for survival when it is revealed that the Far Horizon is a plague ship and that it’s former crew, the victims of a deadly virus, are still very much alive and stalking the corridors of their dead vessel.

With the help of the Android and the ship’s neural link, Five explores the memories hidden away in her subconscious. Navigating the murky, often confusing images that reside deep within her, she uncovers the dark truth about Four and Six’s violent pasts, the circumstances that landed her on the ship, and some insight into the idyllic childhood of a mysterious little boy named Titch.
