Foreign Bodies (1987)

Virus 237 is the most harmful germ warfare substance ever created by anyone at any time, anywhere - and a sealed capsule, itself powerful enough to destroy the world 14 times over, has been accidentally swallowed by failed stand-up comic, Johny Clay. Saved by mysterious, highly-trained, undercover Secret-Service 'cabaret singer', Jenny Taylor, the two now find themselves on the run from an assortment of deadly International Operatives desperately competing to capture Johny and retrieve the capsule with little or no surgical discretion.
