The team investigate a huge gas escape in a residential street as homes are evacuated and a gas worker is trapped below ground. And they're on the trail of fly-tippers blighting one of the most picturesque parts of the UK.

They catch a tipper truck driver on camera as he illegally dumps 20 tonnes of industrial waste in the street, and they are shocked to discover a warehouse crammed with fake goods worth £3 million.
