 Ed, Ros and Beckett (now working as freelance surveillance team  Gizmos ) are hired by the Bureau of Weapons to obtain evidence against Irene Campbell, director of a company which manufactures miniaturised assassination devices. Unfortunately, Irene has just manipulated Beckett into destroying all traces of the evidence. When several high profile people are assassinated, the Gizmos team sets out on a personal mission to bring Irene down. However, Irene Campbell is prepared to do anything to get rid of the team - even if that means resorting to murder.
