Plot summary

Orphaned as boys in a town near the Mexican border, the Heckum brothers took different paths. Buddy, the older, watched his father shot and was taken in by the gangster Julius Hench; vulnerable and described as slow, he grew up to be a killer on Hench's payroll. Jacob plays the violin, is auditioning for the New York Philharmonic and is about to marry his Italian girlfriend, Vittoria. Before the wedding he returns to the town he left, where Buddy has a present waiting for him. Hench is not prepared to lose a man he finds both efficient and easy to manipulate.
