A mother and her daughter are always fighting and screaming at each other. Each thinks that the other has it so easy. Then, thanks to a magical fortune cookie, they switch personalities and bodies and discover each other's problems and complications. And they end up gaining a little respect for each other's point of view. But they need to be changed back by Saturday, because the mother is getting married!

When a mother, Katherine, and daughter, Ellie, are at the most stressful of times, they can only imagine how the other's problems could be more difficult. Thanks to the magic from their late father's hourglass, their imagination becomes a reality when they switch bodies and see what it's like to be the other person.

It tells the unlikely love story of Maddy, a smart, curious and imaginative eighteen-year-old who due to an illness cannot leave the protection of the hermetically sealed environment within her house, and Olly, the boy next door who won't let that stop them. Maddy is desperate to experience the much more stimulating outside world, and the promise of her first romance.
