Los Angeles, 1988. Kate is out with an injured foot, leaving George Frankly to investigate a strange set of pranks. One by one, a different brand of bank falls prey to a prank, and the hoodlum responsible leaves a poetic note on a bank slip. But there's more to the caper than that, as Kate telephones in to say she has looked through the rear terrace. She has seen someone working on plastique bombs.
