Perry Mason - Season 3 Episode 18

The Big Barn is a legal gambling casino run by George Anclitis. Things are going well at the Big Barn until George's second banana, Slim Marcus, botches a crooked card game and is exposed for cheating. Slim's girlfriend, Vivan Ennis, is then killed and George plants a gun and marijuana on Betty Roberts, one of the girls who works at the club. Betty knows quite a bit about the shady activities going on at The Big Barn so George decides to feed her to the wolves in order to take the heat off himself. It's then up to Perry to try and extricate Betty from her predicament.
