When a science experiment goes wrong, Cyd (Landry Bender) and Shelby (Lauren Taylor) become unstuck in time, leaping forward and backward whenever they want--and sometimes even when they don't. With help from their next-door neighbor, teenage genius Barry Eisenberg (Gus Kamp), the girls learn to master their awesome new power as they time-shift through high school. They must also solve a mystery behind a mysterious, scary future lab every time they jump forward in time, where they are strapped to tables and a mysterious hazmat-suit guy who is trying to experiment on them.
