A bumbling group of jewel thieves become the hottest thing since The Wiggles after dressing up like a children's singing group in order to snatch a priceless necklace. Danny (Nick Giannopoulos) isn't much of an entertainer, so when Marcus (Russell Dykstra) tries to recruit him to lift a necklace from wealthy Aurora Van Dyke (Lena Cruz) he senses an opportunity for some quick cash. Aurora has scheduled a birthday party for her child, and the best-loved children's performers from miles around are coming in for the big event. When the heist hits a hitch and the robbers ditch the necklace to make a daring escape, they thought their ordeal was over. Little did they realize that their group, The Wannabes, made quite an impression at the party, and they've since developed a nation wide following. Now, as Aurora attempts to prove that it was they who tried to swipe her necklace, Marcus does his best to win the heart of Kristy (Isla Fischer), the head criminal ringleader's sister. ~ Jason Buchanan, Rovi
