A double-episode special. To gain crucial knowledge to enable the theft of trans-warp technology from a crippled Borg ship, Seven of Nine must endure the painful task of analysing the journals of her own parents who were Borg experts. Meanwhile, training for the dangerous mission is underway in the holosuite to perfect the theft so that the away team will stay undetected by the drones. On the eve of the theft, Seven of Nine is contacted by the Borg and their Queen who offer her an ultimatum: rejoin the Collective or watch as Voyager is assimilated.
