Gun tells the story of Mark, a boy struggling to come to terms with an abusive homelife and the lengths he will go to escape.
Mark has grown up watching his mother being beaten up by his father. Unable to make sense of her persistence to stay with his father, Mark turns to his friends for the support he needs to make it through the days. With Karen he finds both support and love but even this is not the solution to his family situation. After a run in with the law they find themselves at the door of Ruben, a local drug dealer.
It is here that Mark finds the answer he has been looking for when Ruben shows them his latest acquisition, a handgun. He steals the gun and returns home, ready to end the violence forever. Gun is the first film in the Short Circuit series, a scheme for the production of short films by local first time writers, directors and producers.
