Susy Hendrix is a blind Greenwich Village housewife who becomes the target of three con-men searching for the heroin hidden in a doll, which her husband Sam transported from Canada as a favor to a woman who has since been murdered. "Roat" leads his companions into thinking they are going to be rich and will get the heroin soon enough, but in the end he murders all of his partners after they outlive their usefulness.

The trio try to convince Susy that her husband has been accused of drug smuggling, and the only way to protect him is to give them the doll. Little do the men know that Susy gave the doll to Gloria, a little girl in the upstairs apartment.

One of the men plays a man named Sergeant Carlino, a strange police sergeant/detective, while another plays Mike, a supposed old friend of her husband dropping by for a visit. Susy relies on "Mike", and he eventually begins to feel sympathetic for her.

'Roat" plays both Mr. Roat and his "son" Roat Jr. Roat Junior ransacks her room and steals from her. He threatens Susy and her husband's well being, so she calls the police, or thinks she's getting the police. Of course, the con-men knew this would happen and send over "Sergeant Carlino".

Susy is incredibly clever, and with the help of Gloria, she realizes the true identity of the men and plans to defeat them.

The stage lights are turned off for the final scene, when Susy turns off all the lights so that "Roat" can't see her. "Roat" threatens Susy and tries to kill her. She ultimately kills "Roat", while Gloria goes to the police.

At the end of the play, Sam bursts in with the police to find that she has already taken care of Roat, and he sees Mike was also killed in her apartment. The police go to help Susy, but Gloria yells at them, saying she can do it on her own, and helps Susy get up. The final image of the play is Susy and Sam embracing by the stairs.  (Wikipedia)
