Two guys meet, one American, a deserter from the US army, one Brit, and they are drawn together by their mutual love of Soul music. Neither being gainfully employed they decide to start a mobile disco service for fellow soul lovers, which leads them to buy an ice cream van, and the adventure begins. Before long they find themselves on the run from the bad guys and the police.

The lives of Bodie and Doyle, top agents for Britain's CI5 (Criminal Intelligence 5), and their controller, George Cowley. The mandate of CI5 was to fight terrorism and similar high-profile crimes. Cowley, a hard ex-MI5 operative, hand-picked each of his men. Bodie is a cynical ex-SAS paratrooper and mercenary whose nature ran to controlled violence, while his partner, Doyle, comes to CI5 from the regular police force, and is more of an open minded liberal. Their relationship is often contentious, but they are the top men in their field, and the ones to whom Cowley always assigned to the toughest cases.
