When a blizzard barrels down on Salt Lake City, the Wildcats are stranded at East High after hours, just as E.J. receives some bad news. As cabin fever sets in, Miss Jenn inspires Nini to make a bold choice about her future; Kourtney's coworker Howie makes a surprising move; and Gina and Carlos come to blows.

After rival school North High releases a viral video to undermine the Wildcats, Miss Jenn hosts a weekend improv intensive to build up her kids' confidence. Meanwhile, Nini works on a new song at Salt Lake Slices, where she finds inspiration in Kourtney's approach to life.
