Set in San Antonio’s Westside in 1979, Chato's Bridge is a gritty but not gratuitous look at the harsher aspects of barrio life portrayed by these two lifelong friends, Chale and Simon, whose loyalty to each other and their lost friends is absolute, as is their drive for vengeance. They must carry out their retribution before the undercover cop who has infiltrated their gang shuts them down. Unknown to them, a long-lost figure from their past is serving as their guardian angel.
