Constable Stu Ellison and police dog Edge are called to a house where an intruder has smashed a window and fled the scene. Edge picks up the scent and gives chase. Constable Cherie Banks and police dog Shilo spend a long hot day searching suspected drugs dealer’s houses. It’s the final day of the annual police dog trials, and dogs Nat and Luger are the final two left battling it out to become top dog. It’s a test of strength, fitness and trust between handler and dog.
