Everyone in Darwin Family has been victim of vicious pranks!! A culprit comes and leaves cereals in beds, fruit salad in Bethan's shoes and ‘loser' written on Chris's head in permanent marker. Of course Drew and Staggsy are automatically blamed for this. But it is up to them to figure out the whodunit. They decide to have a stakeout to figure out who did it. They set nets to capture him and turn on a video camera. However it turns out that the person who had done it was acutally...gasp...Drew. He was sleepwalking--a thing that happens to young people when their parents decided to split. Meanwhile, Tally is failing Design class. She decides to keep the secret from Bethan and instead tells her than she and Daniel the design teacher are dating. Bethan finds this repulsive and tells Eddie, who then tells Daniel. Daniel tells Tally that she almost ruined his career. Bethan also tells Tally that if Tally weren't so jealous of her none of that would have happened.
