In this action comedy, we follow the misadventures of a tough and somewhat clumsy police detective, Officer Mike Dooley, who faces one of the most unexpected challenges of his career: a scrappy and energetic canine partner named Jerry Lee, a German shepherd with a natural talent for getting into trouble. After a major drug lord crosses their path, Dooley realizes he needs all the help he can get to catch this criminal. Reluctantly, he accepts Jerry Lee as his new partner in the fight against crime.
The relationship between Dooley and Jerry Lee starts off tense, as the detective is not used to working with an animal, but they soon discover that together they make an unbeatable team. Amid doses of humor and absurd situations, such as car chases where Jerry Lee proves to be more agile than his human, the duo delves into the underworld of drug trafficking. The dog's blunders lead to hilarious situations, from unexpected escapes to confrontations with the most dangerous criminals.
While Dooley tries to maintain his professionalism and keep the situation under control, Jerry Lee puts his loyalty and bravery to the test at every turn, helping to cement a heartwarming bond between them. In the end, the detective not only manages to apprehend the villains but also transforms into a better human being, thanks to the lesson in unconditional friendship taught to him by his four-legged companion.
