Gus and Callie are babies with a difference. Fueled by a mutual hatred, they seek to cause each other as much distress as possible. A toddle in strollers becomes a 90-mph race of epic Ben-Hur proportions, playgrounds become death-match arenas and an innocent hamster becomes the weapon of choice in a John Woo-style shoot-out. Filled with comedic violence and changing battlegrounds, if you're looking for cute and cuddly you've come to the wrong playpen!
