The film follows the story of Cláudio, a successful publicist who owns his own agency, and Helena, his wife, a music teacher who takes care of a children's choir. Accustomed to the day-by-day marriage routine, they occasionally argue. One day they have a bigger fight than normal, which causes something inexplicable to happen: they switch bodies. Terrified, Claudio and Helena try to appear normal until they can reverse the situation. But to do so they will have to fully assume each other's lives.[2]
