An honest girl called Cara aims to recover her family jewellery (which has been consfiscated as a result of a lover's tiff) by stealing it from a hidden safe. She hires the ultra-cautious safebreaker Sam to do the job for her, and persuades him to take her along. Realizing that Cara will be a danger, he insists she must follow his orders. The plan is for them to dress as students and make their getaway by mingling with college crowds... But Sam has made the first big mistake in his long and successful career as a peterman.
