As he struggles to get back on his feet after the horrors of service as a medic in the Middle East war, Roy Dunham tends bar in a quiet club. The sudden entrance of K-9 Officer Samson, a Belgian Malinois, and his handsome "human" partner Craig Rommel startles Roy, and the cop's attitude puts him off. Roy's opinion soon changes, however, after Sam and Craig save him from drug-driven violence. He returns the favor by tending their gunshot wounds, and before long, Roy finds himself hoping the policeman and the dog will become permanent parts of his life. Can Sam be the key to winning Roy's way into Craig Rommel's well-protected heart?
