The Showtime drama Yellowjackets is a series in two halves: In the first part, a plane crashes in 1996, and a high school girls' soccer team is stranded in the Canadian wilderness. The other part follows some of the girls more than 20 years later, as they realize the full ramifications of what they did during the time before they were rescued. Part horror and part suspense, Yellowjackets boasts a killer cast and a tangle of dark mysteries at its heart.
