The Yellowjackets barely made it through summer in the woods, but now as winter begins to bite, we’ll see if hunger and desperation turn into full-on psychosis. While there may or may not be a dark and powerful force inhabiting the wilderness, their survival could depend upon what they choose to believe. Meanwhile, twenty-five years later, each survivor must ask themselves – Is the darkness coming for them, or is it coming from them?

Summer inspires the Yellowjackets to ditch soccer for a more contact-intensive sport and revive an old pagan tradition. In the present, a cringe-worthy funeral flows organically into a bar therapy session.

The return of a Yellowjacket sparks a vengeful frenzy in the team. Lottie's rendition of Cool Aunt Without Kids leaves Callie with an open door to answers about her mother's twisted past. Tai and Van receive a karmic payout for their dine and dash.

With a possible escape from their nightmare, the Yellowjackets learn not everyone may be in a rush to leave. In the present, the unexpected return of an old teammate sends Shauna spiraling in ways that should probably concern everyone.
