If you were given the power to prevent every high schooler's worst fear from happening, would you risk everything to stop it? As Sienna (SJ) Johnson and Ashton Blackwood, estranged childhood friends, start their freshman year of high school, they are forced to do just that. Popular SJ is on track to be the top of her class and attend an elite dance school on full scholarship, while simultaneously trying to stop her parents' marriage from falling apart. Ashton is just trying to get through life after the sudden passing of his father, which leaves his mom and him in financial ruin. When SJ and Ashton are forced to work together as biology partners, their lives are flipped upside down, quite literally. SJ and Ashton are thrown into an alternate high school universe, much like theirs, but with one significant difference: their roles are reversed. Ashton is now the school's golden boy, while most people can't even remember SJ's name. When a catastrophic event takes place at the flip school, they realize it is up to them to prevent it from happening at their school in order to save lives.
