Meet Mae Cannon, a 30-something-year-old who is in a marriage that totally works. She and her husband, Elijah, have been together for 13 years, There's a lot of love there...but not a whole lot of excitement.

One night, Mae has a temporary lapse of judgement and meets a hot man at a bar and ends up sleeping with him... She wakes up the next morning in his apartment in a panic and realizes that she has somehow slipped into a parallel universe, married to the same man she cheated on her husband with. It’s incredible. Suddenly the grass that was so much greener has a slightly different hue, as she's now actually standing on it...for eternity. Except it's not really for eternity, because episode to episode she continues to slip into parallel universes, entering new relationships, trying to find her way back to her partner, and ultimately, herself.
