Star Trek: Voyager, Series 7, Episode 15.
First broadcast on Wednesday 14 February 2001.

This week we drop into a parallel universe where Voyager’s situation is desperate, resources are constrained, and the crew has no alternative but to live by its principles — helping, making friends, reaching out, forming alliances, working together to solve problems, seeking out new life and new civilisations, that sort of thing. Turns out, it would have made quite a good premise for a Star Trek series.
