In Australia's own version of the popular series, Aussie host Scotty introduces a prankster who is on a mission to prank someone they know - a friend, sibling, parent, teacher, maybe even their entire karate class! In the customised Spy Van, Scotty and the prankster plan out the prank - first the prankster reveals who they want to prank and why. Then Scotty and the prankster choose the perfect prank from the Top Secret Prank Patrol files. Whatever the challenge, Scotty and the Ninjas will find the right ingredients - special effects gurus, actors and a location - and then build a prank the victim will never forget! Prankster sisters Ashlee and Chloe call in the Prank Patrol to help them fool their granny into thinking she has a shoplifting double that is getting her into some major trouble! Ashlee invites Grandma to visit a great homewares store where she accidentally slips a bracelet into her pocket setting off the store alarm, resulting in the two of them being questioned by a police officer - and it turns out Granny is on the 'Wanted' list and there's photo evidence of her committing the crime. But what will happen when everyone discovers that Grandma has a thieving twin who is her granddaughter in disguise?
