Young lovers and small-time New Orleans scammers Coco Chavez (Carla Gugino) and Junior Armstrong (Simon Baker-Denny) move up a few rungs when they kidnap wealthy computer mogul Ben Dyson (Greg Wise) in Sebastian Gutierrez's neo-noir. During the crime, Coco kills Dyson's girlfriend, Patty (Beverly Penberthy), wife of Senator Rupert Hornbeck (Hal Holbrook). Assigned to the case are FBI Agent Sadie Hawkins (Emma Thompson) and Police Lt. David Friedman (Alan Rickman). When Hornbeck threatens Friedman instead of assisting him, the detective suspects that this is no ordinary kidnapping for ransom, and he does his own investigation. A conscience-stricken Coco realizes that she may have been set up to kill Patty, and she, too, takes matters into her own hands. A fairly complex tale of betrayal and corruption, Judas Kiss also spoofs noir conventions -- for instance, agent Hawkins is reading Jim Thompson's crime novel {-The Killer Inside Me}, and he discusses the writer's works with Friedman during lulls in the action.
