The Cul de Sac presents an apocalyptic world where the adults have disappeared. In this first episode, Rose (Greta Gregory) realises something is very wrong when she leaves home. Meanwhile at the local high school, dictator in the making Doni (Simon Mead) refuses to let anyone inside the building. Rose's sister (Molly Leishman) is in danger of having a medical emergency, Jack (Riverdale's KJ Apa) proves he isn't completely useless, and a dog goes rabid. Created by Stephen J Campbell (Amazing Extraordinary Friends), the sci-fi adventure spanned three seasons.
