Star Trek: Voyager 6.8 - Tsunkatse/Collective

Tsunkatse While on Shore Leave, the crew of Voyager are drawn to a strange and cruel sport called Tsunkatse, in which two contestants fight hand to hand until one of them is unconscious or even dead. However, the 'Starfleet Officers' excitement turns to horror when a newly announced death match contender is revealed as Seven of Nine. Collective Taken hostage by the Borg cube, Chakotay, Kim, Paris and Neelix's fears of assimilation become even deeper when they realise that their captors are immature Borg drones who do not have the skils to carry out assimilation without murdering their subjects. Seven of Nine is despatched to negotate with the dangerously upredictable Borg children.
