Seven of Nine is led to a place known as Unimatrix Zero; a place where Borg drones are individuals for a short period of time during their regeneration. However, once their regeneration is complete, all recollection of the event is erased. Captain Janeway uses this to form a plan of attack that would create a mutiny from within the Collective.
While chasing a renegade Maquis ship in the Badlands, the USS Voyager and the Maquis ship they are chasing are pulled into a vortex, which sends them instantly to the Delta Quadrant. However, after the destruction of the device that transported them to the Delta Quadrant, the crew of Voyager and the crew of the Maquis ship must join together to fight their way back to their home in the Alpha quadrant, which is many years away. They will meet many foes and many obstacles along the way, but they will also bond as a crew, between those of the Maquis and those of Starfleet.
