Kate is not happy when Simon is allowed to go to a rock concert but she is banned from going by her parents. Kate's accusations of sexism are dismissed by her mother Sarah, but when the family go to a car showroom to buy a car Sarah has cause of her own to complain.
Frustrated at how the family laze about during the school holidays, Sarah decides that they will do something together as a family. The rest of the family, however, are not happy and even less so when they discover that her choice of activity is to visit a museum. But it proves anything but dull when the dreaded hypnotist's curse strikes when they least expect it.
