Jake Kasdan made his feature film directorial debut with this oblique thriller about eccentric private detective Daryl Zero (Bill Pullman) and his sardonic front man partner Steve Arlo (Ben Stiller). After the two are hired by blackmail victim Gregory Stark (Ryan O'Neal), Zero sets up a sting operation and soon focuses on his suspect, Gloria Sullivan (Kim Dickens), a woman he met at a health club. Thinking Zero is an accountant, she asks him to look over her tax return. Clues form a trail to hitman Kragan Vincent (Matt O'Toole), who could be Gloria's father. Amid the romance and revenge, Zero manages to write a few songs (actually written by Pullman and Kasdan).
