Aunt Clara is a 1954 British comedy film starring Margaret Rutherford as a woman who inherits a number of shady businesses from a relative.

When her cantankerous uncle Simon dies, he unexpectedly leaves her the bulk of his considerable estate - his house, six racing greyhounds, a crooked game, a pub and a brothel - because she alone would see to the well-being of those dependent on him, and was the only one looking after another when he held his 80th.

She also discovers that Simon's "natural daughter" Julie Mason, to whom he left £20 a month for life, has disappeared.

Clara decides to have her solicitor Charles Willis try to find her, only to discover he met Julie at the funeral and is dining with her that very evening.

Then she learns that Fosdick, the man operating the crooked Gambler's Luck wheel of fortune, will be at Epsom Downs, so she goes to meet him.

Next, Alfie and Lily Pearce deceive Clara into believing that the greyhounds they are training for her are champions, the furthest thing from the truth.
