At Balaclava Agricultural College, a kidnapping and pig-napping are followed by murder. Newlyweds Peter and Helen Shandy are picking out flatware when a pair of gun-toting hooligans burst into the silversmith's shop, empty the safe, and leave with Helen as their hostage. Although the police recover Helen quickly, her professor husband is badly shaken by the ordeal. Early the next morning, the college's head of animal husbandry frantically reports another hostage situation in progress. Belinda, the school's beloved sow, has been kidnapped, and only Peter can bring home the bacon. There is a possible witness to the pig-napping in Miss Flackley, the farrier, but before she can point Peter towards the vanished porker, she is found dead in the barn's mash feeder. By the time Peter discovers the link between the two heists, pigs may really fly.
