DANNY (Nick Giannopoulos) never had much talent. But that didn’t stop him devoting his life to the performing arts. His career – teaching at his mother’s talent school – is going nowhere when he is asked to teach a bunch of wannabes how to sing and dance. Hardened crim MARCUS (Russell Dykstra) tells Danny he and his shady friends want to be a children’s group. Their real ambition is to crash a party that local billionaire MRS RORY VAN DYKE (Lena Cruz), is throwing for her grandson and make off with her three million dollar diamond necklace. Danny takes one look at the crooks’ immense lack of talent and turns them down. Then he takes a long, good look at Marcus’ gorgeous sister KIRSTY (Isla Fisher) and decides the gang might have something he can work with after all.
The Wannabes, Australia’s first politically incorrect children’s group are born. Come show-time, a last minute injury means Danny is forced to become part of the act. The theft is bungled but the Wannabes are a hit. They’re armed and hopeless but the kiddies love them. They are swamped with bookings and soon they are making TV appearances, magazine covers and chart-topping CDs. Finding themselves in a lucrative new profession, these crim’s can afford to give up their day (or night) jobs. But the past has a way of catching up to you. Soon The Wannabes are back in the crime game putting their newfound careers, fame and fortune – not to mention the joy of thousands of little fans – all on the line.
