Time's running out for senior BFFs Erika and Gia to live their best high school lives. A house party feels like a last chance - and final destination.

Life as a dead person is a lot. Erika needs the facts but must pee first. Can she get solid spiritual advice from teens who see signs in pizzas?

After ghosting Jake C., Erika needs to deal with her unfinished business. With promposals and paranormal activity in the air, the end is near. Maybe.

Kissing away unfinished business can be fun, but questions remain. Prom looms, but Erika will have to ask fast. In the excitement, Gia feels unseen.

Word gets out: Erika's cool, not chill - and the queen of Parkway. But the pressure's on as the temp rises, frenemies square off, and a troll surfaces.

Life after passing has never been so - popular. Gia confronts Erika and connects with Gavin. All hell breaks out when BFFs turn and the truth emerges.

YOLO - or do you only live twice? Two besties get real while confessions fly. Old footage and a new hashtag threaten Erika's fame.

The afterlife comes calling. A will scribbled on a Forever 21 receipt, a hoped-for prom date, lava lamps: the power of friendship must shine through.
