Wallace and Gromit were planning to take their holiday in Blackpool, but the weather is miserable and so they have to cancel. Wallace gets the idea into his head to turn his flooded basement into a beach, and then he thinks he can profit from it by inviting everyone over. It's not long before it all goes horribly wrong and the team must try to prevent everyone from wanting a refund. After that's dealt with, the game enters an odd "whodunit" story of who hit a character. The answer is laughably obvious, but trying to prove it is a little difficult.
