The story finds our canine hero Charlie (CHARLIE SHEEN) in dog heaven-literally–where he should be enjoying his afterlife. Unfortunately, he has decided that, though his reward may be in heaven, it’s a lot more fun scamming for it back on earth. Charlie gets his chance at a return trip to earth when Gabriel’s Horn is stolen and falls from Heaven, and he is assigned to retrieve it. Reunited with his old pal Itchy (DOM DELUISE), Charlie is also joined in his quest by a beautiful Irish Setter named Sasha (SHEENA EASTON) and a young runaway boy named David (ADAM WYLIE). The reluctant canine angel Charlie proves to be more worthy of his wings than even he imagined as he battles the foul feline Red (GEORGE HEARN) and the traitorous bulldog Carface (ERNEST BORGNINE) to regain the precious horn and save heaven.
