A poorly planned attempt at a frozen fraud melts away when investigators turn up the heat, while a prisoner claiming for injury behind bars forgets that the camera never lies. A foul-mouthed fraudster confesses all when a botched attempt to cash-in backfires, a bodybuilder is floored after flaunting his workouts when he's supposed to be off sick, gang members are caught buying bogus car cover from a business that's less than squeaky clean, and social media catches out a cheeky claimant.

Secret filming is the undoing of a greedy opportunist attempting to grossly exaggerate his personal injury claim, and sparks fly when a claim for a solitaire diamond isn't as clear cut as the claimant would have insurers believe. CCTV proves to be the ultimate eyewitness when an umbrella in a pub garden is accused of being drunk and disorderly, a claim for a mobile phone turns into a family affair, and insurers deal with a rear-end shunt that has plenty of twists and turns.
