Comedy following the exploits of four 20-something London flatmates, Jack (David Raymond), Oli (Richard Sumitro), Nick (Brendan Patricks) and Sam (James Corden), who devise a wild moneymaking scheme. They cater to clients who suspect the infidelity of their loved ones, by hiring phoney male and female suitors to deliver pick-up lines and 'test' the faithfulness of the partners, while the men secretly videotape the come-ons. They then deliver the videotapes to the clients. The scheme works brilliantly, until Jack manages to unveil his ex-boss as a cheater and a chauvinist, and irritates one of his own conquests, Hannah (Jenna Harrison), in the process. Further problems arise as Jack's guilt grows about the negative impacts of his business on its victims - compounded by the fact that one of the upcoming 'jobs' involves his own mother (Jenny Agutter).
