Cesar helps Krystal and Anthony, whose athletic Vizsla mix Tic Tac threatens to get them kicked out of their home in the marina, and Evan, whose German Shepherd mix is creating havoc with his motorcycle buddies.

Cesar is confronted with a one-eyed rescue mutt, Duk Duk, who is so distrustful of humans, that he attacks out of fear. He has bitten his owner, her mother and her father. He now needs surgery on his leg, but the owner can't get him into the car. Cesar has his hands full and is even willing take a painful bite to teach Duk Duk to stop attacking humans and get the leg surgery he desperately needs.
