Tammas is twenty, a loner and a compulsive gambler. Unable to hold a job for long, his life revolves around Glasgow bars, home with his sister and brother-in-law, the dog track, betting shops, casinos and occasionally a day at the races. Sometimes Tammy wins, more often he loses, but betting gives him as good a chance as any of discovering what he really seeks from life since society offers him no prospect of a better or more fulfilling altenative.
