Tipped off by his buddy (David Johansen), a loser cabby (Richard Dreyfuss) parlays a $50 horse bet at the track. Luckily, he wins big, but he can't seem to stop gambling. Will he go broke or walk home with a pretty penny?
Only in the movies can you come across selfish bastards that you actually like. Of course it helps when your bastard is played by the likes of Richard Dreyfuss.
