Project 001: The Great Time Loop

A group of time travelers have been stuck in 1982, reliving the same 30 seconds for eternity.

Day 1: The travelers are stuck in the middle of a high school prom.
Day 2: A group of punk rockers try to teach the time travelers the art of safety dancing.
Day 3: The travelers discover they are not alone, and there's an ancient civilization living in the walls.
Day 4: The travelers try to contact their families, but all they get is answering machines.

Will they ever escape, or will they forever be stuck in this loop of 80s nostalgia?
