The Yellowjackets pilot runs viewers through a gamut of emotions at an athletic pace, using dual timelines to introduce the young women of the Yellowjackets, an undefeated high-school soccer team on its way to nationals in 1996, and also show how their lives look 25 years after surviving a plane crash en route to that very game.  A remote portion of Mammoth Mountain Resort stands in for the Canadian wilderness during flashback scenes - to access set, crew members had the option to travel via Snowcat cab (toasty but slow) or the back of a snowmobile (nippy but zippy).
