Part 3 starts with Sarge sunbathing on the beach at Zanzibar, when he receives an urgent phone call from Simmons. Grif is refusing to help defend the base, due to his new beliefs, so Sarge offers up an unhelpful plan. Simmons eventually decides to negotiate with the Blues, who admit they are only attacking in order to keep warm, which Simmons uses to negotiate a ceasefire for the holiday. The episode ends with the teams standing around a large fire, remembering previous mishaps, and wishing each other a happy holiday. (thetvdb.com)
