Dark Frontier, Part II

The Borg detect her plan and access Seven Of Nine's neural transceiver to deliver an ultimatum: rejoin the collective or the ship and its crew will be assimilated. The ship will be guaranteed safe passage through Borg space if she agrees. After she agrees to rejoin the Borg Collective, the Borg Queen attempts to put her to work helping the Borg. Janeway launches a rescue mission to save Seven of Nine from being re-assimilated by the Borg.
