Poolboy: Drowning Out the Fury.

In this unearthed lost movie from 1990 that the studio deemed too terrible to release, a Vietnam Veteran Sal Bando(Sorbo), tortured by his past as a Poolboy returns home to Van Nuys, California, and a country he doesn't recognize, in which it seems only Mexicans run pool-cleaning companies. Bando sets off on a brutal mission to reclaim his "rightful" vocation and enact revenge on the man(Trejo) who killed his wife and son.
