Bogart is in jail. He’s been there before, but he never felt like he deserved it until now. Peeing on the carpet is one thing, but now he’s killed a man. And it wasn’t just any old man–any old man may have been forgiveable. Bogart killed Swifty’s father, and Swifty is Bogart’s human, so now he deserves his jail sentence. Now he deserves a death sentence. He’s truly a bad dog.
In an effort to give Swifty back the part of him that he took away, Bogart escapes and embarks on a journey to recover the dead man’s Red Sox hat. Joined by his border collie girlfriend, Ginger, and an abandoned kitten named Snowball, the three of them set out to become good again.
