September 22, 1975. The sun blazes over San Francisco. On the pavement in front of the St. Francis Hotel the excited crowd eagerly awaits the arrival of Gerald Ford, the 38th leader of the Free World. Nobody notices the woman who tries to push her way to the front, carrying within her purse an old revolver, tucked away between her chewing gum and a couple of starched handkerchiefs.

Billy, Sally, Jerry and the .38 Gun zooms in on an almost forgotten event in recent American history when politics, terrorism and the LGTBQI Movement unexpectedly collided.
