While helping Martin do some work, Tim accidentally magnetizes Martin, turning him into a living magnet. Martin is able to demagnetize himself, however his magnetized particles are spilled onto the hands of Mrs. Brown's new handyman, reformed pickpocket Andy Fuller. Andy really wants to make it on the outside, but his new magnetized hands are causing some problems when they're attracted to Mrs. Brown's new metal brooch. Andy thinks it's all his fault. His magnetic hands are however mixing with the habitual side of his brain, and are also attracted to non-metalized items of value, such as Det. Brennan's leather wallet. The magnetism is only temporary and thus Martin needs to keep Andy out of trouble for only 1 more hour. If only Mrs. Brown would stop putting Andy into compromising positions, Martin's job would be that much easier.
