Eccentric Louise McHugh is delighted to learn her new neighbor is a well known racketeer, Johnny Trovado. One day three people invade her home on one pretext or another: a telephone repair man, a high fashion wedding consultant (her daughter is to be married shortly) and the father of the groom a stranger. Louise gradually realizes their identities are false. The three villains state to an amazed yet pleased Louise they are holding her prisoner while they plant a bomb in the Trovado house. Louise, her maid and her brother, a priest, employ inept plans to thwart the villains with spectacularly ineffective results. Moments before the explosion a plan works and Louise waits impatiently for the media cameras to arrive.
