Aqua is a dog who works hard on an Australian farm, herding sheep and helping the farmer. However whenever he gets the chance, he runs off to the water hole for a quick paddle. He likes nothing better than to swim, splash and dive beneath the surface – but the farmer just doesn’t understand. Aqua often gets in to trouble for indulging his passion for swimming!

One day, the farm is hit by a terrible storm and the rain soon causes a flood. The farmer doesn’t know what to do but Aqua Dog springs in to action. He dives through the water, and like a hero, he rescues every sheep. Once his rescue mission is complete he looks around for the farmer but he’s nowhere to be found. Aqua soon realises he must be underwater and he can’t swim! Can he rescue him before it’s too late?
