Teenager Danny needs the distraction from visiting a leisure park, being constantly bothered by his penniless mother and siblings, including a baby.

The boys are eager to switch places, tasting the other lifestyle, before things get complicated, involving entry to celebrity Thore Schölermann's guitar talent hunt and finding out they are twins, separated for adoption.
