Perry Mason - Season 7 Episode 30 : The Case of the Ugly Duckling 1966

The deceased father of Alice Trilling left behind a strange will. His successful toy company would be left to her ONLY if Alice is married or engaged within a year's time. Until then, her wheelchair bound Uncle Harry and a board of directors will run the company. In searching for a husband, Alice has one major problem: she's coyote ugly and she's the first one to admit it. An artist begins a flirtation and after seeing a portrait he's painted of her, Alice begins to think she could find happiness with him. There's one problem though: nasty old Uncle Harry has been playing matchmaker behind the scenes for reasons of his own. Alice discovers her uncle's perfidity and pushes over his wheelchair. Quickly fleeing the scene, Alice is later arrested when Uncle Harry is found dead. Perry is retained as defense counsel but even he has a tough time in this one because Alice herself thinks she's guilty.
