Driving home from an LA Lakers game, Mack (Kevin Kline), an immigration attorney, is stranded in an unsavory part of town when his car breaks down. He is rescued from a gang of hoods by Simon (Danny Glover), an African-American tow truck driver, inaugurating a friendship between these two men. Mack offers to repay Simon's kindness by helping his sister (Tina Lifford) finance her move to a better neighborhood, and by arranging a blind date between Simon and Jane (Alfre Woodard), a friend of Mack's secretary (and ex-lover) Dee (Mary Louise Parker). Woven into this fabric are the tribulations of Mack's best friend, a pompous exploitation movie producer (Steve Martin), who is later wounded in a robbery similar to the one threatening Mack at the beginning of the film; of Mack's wife Claire (Mary McDonnell), who adopts an abandoned baby, and disenfranchised son Roberto (Jeremy Sisto); and of Simon's nephew (Patrick Malone), who is contemplating joining a street gang. The title is symbolic, referring to the class-imposed chasms which would normally separate the characters.



Director Lawrence Kasdan's 'Grand Canyon' is a gathering of random events, uniting the film's wildly divergent protagonists.
