Dominic has decided it is time for a change. So, the young dog packs up his hats and his piccolo and sets off into the unknown. But no sooner does he feel the air on his snout and the grass beneath his paws, than he encounters the dreaded Doomsday Gang. Fortunately, Dominic is not one to complain – and nor is he one to lose a fight! As word of his victory over the criminals spreads, more and more animals turn to him for help, including a 158-year-old turtle, a heartbroken wild boar and a family of geese. But can one brave dog face the Doomsday Gang alone?
