Tribes tells the story of an African American, an Arab-American and a white guy who try to rob a subway wagon. Because none of them wants to rob people of their own race, it sets them off to a series of arguments over self-identity. This leads the would-be bandits to continually divide the passengers into various ethnic, cultural and economic subgroups in an effort to find a class of people that none of them identify with - a group they can feel good about robbing. When the train arrives at the next station, no one expects that the situation would be reversed. Self-identity is truly a bitch.

On the new Arrow blu release (and on the previous Scream Factory release), this feature-length making of takes a fresh approach to most similar docs by focussing on the actors and the actors alone. New interviews with all the main cast show the tremendous amount of love all had for the project and how it was Barker's wonderful characters that drew them all in. They spend a significant amount of time with each actor exploring their respective characters, delving deep into each, detailing exactly what each wanted to bring to the film.
