Sock hops. Soda fountains. Slumber parties. Life in 1955 is simple for tomboy Beverly, moody Maxine, high-spirited Judy, studious Mary, and artistic Ann. But after a class assignment to predict life in the future, they wake up the next morning in a future they could never have imagined, having time-travelled into a parallel universe over fifty years into the future. With only each other to trust, they must work together and find their way home to 1955, but the more they discover about the future, will they even want to go back?
