From The Perry Mason TV Show Book (Revised)
An episode with good shots of the street hustle and bustle of the fifties, but also troubling for how easily men could abuse the women who worked for them during this period, especially in entertainment.
The Big Barn is a legal gambling casino where "everybody is happy" under the orders of the big boss and laughing boy George Anclitas. That is, until second banana Slim Marcus botches a crooked card game and is exposed for cheating.
When Slim's girlfriend is killed, Anclitas plants a gun and marijuana on Betty Roberts, one of the "skirts" that works for him. Betty knows too much and Anclitas wants to use her to take the heat off his club and his "boys." Perry takes Betty under his wing and goes to great lengths to put the real criminal where he belongs.
