Munroe is military dog, though not the best trained dog ever, he has two good human friends.
In camp Boone K-9 Division of the U.S. Army, Munroe is not exactly the best of trained dogs. Gitchy and Ira, his trainers, are summoned by the Colonel. He gives them 48 hours to train Munroe to not chase the Colonel's mother-in-law's cat. Their idea is to lead him to a lion so he becomes scared of felines. The plan backfires when the lion breaks loose in the camp.
