Deep in the jungles of Paradise Falls resides a dog pack on a mission to capture a rare bird that its master is pursuing. Just like their rejected comrade Dug, all the pack dogs have high-tech collars that give them unusual abilities especially designed for sinister hunting expeditions, including GPS tracking and translating their thoughts into speech.

Alpha, the pack leader, is a menacing-looking, black-as-night Doberman Pinscher with authority entrusted to him by their master that no one dares question. Beta, a tough Rottweiler, is Alpha's lieutenant, and Gamma, a rough-and-tumble bulldog, is his hench-dog. Nothing will detract the pack from its mission—except maybe a squirrel.
