L.A. Heat - Season 2 Episode 20 Legacy of A Buffalo Soldier

A Western memorabilia collector is found murdered, and among the victim's belongings is a laptop containing August's name. August figures out that his name was listed among the descendants of Buffalo Soldiers, a special troop of black soldiers that fought during the Civil War. This brings up a part of August's past that he is ashamed to discuss: his great-great-great-grandfather, Augustus Brooks, was given a dishonorable discharge from the Army when he allegedly deserted his troop with three other soldiers, claiming to have been given a map leading to a gold mine that was never proven to exist. August's Aunt Maisie is attacked in her home by a thug, hired to steal a portion of the old map. The pieces have been handed down to each generation, and now someone is attempting to put the pieces together and lay claim to the gold.
