A scam that started with a car crash, designed to line pockets, backfires badly. A greedy claimant uses a burglary as an opportunity to exaggerate his claim, while friendships are tested as skint students resort to fraudulent measures. Business partners bending the rules are caught out by social media, a motorcyclist entangles himself in a web of deceit, and a sprinkler scam leaves an opportunistic fraudster in deep water.

Undercover filming exposes one man's attempt to cheat his way to a one-million-pound payout, while a claimant's photography skills come under scrutiny as she attempts to claim for some lost jewellery. A would-be fraudster attempts to extend her home insurance claim, and an absent-minded opportunist persists in a claim over a lost bag. A prisoner earns himself additional time behind bars when his slippery scam trips him up, and CCTV proves to be the ultimate eyewitness as a motorist does battle with a bus.
