At Terminal 3 Immigration Officer Lisa Lea check the passport of a man from Pakistan who says he's here to do some marketing for his fruit and veg business. Lisa is suspicious from the outset when she looks at his passport stamps. She finds out he's living in Britain and running businesses based in Britain. This is illegal.

An Indian student is stopped at passport control. He says he's not working but pretty soon Immigration Officer Neil Newbury finds out he's working at Tesco supermarket stacking shelves. The man is caught out and returned home on the next flight. Officer Steve Hassler stops an American who has come to Britain to teach puppetry.

In India the visa applications for travelers to Britain are decided by a small group of Brits on a 2 year posting in New Delhi. We see them interviewing suspect "students" and other potential visitors like the 35 year old Punjabi who's just married a 60 year old Welsh woman. The visa officers at the high commission suspect a sham marriage, but can they find any proof?

This must be the boldest enforcement operation. Street Ops, as they are known, involve a group of immigration officers in full immigration uniform trying to spot illegal immigrants amongst in busy streets. In this episode we follow two Street Ops. The first at North Greenwich Tube Station, where a man is stopped and questioned but then wriggles free and runs.

It's 8am and Immigration Officer Bridgette McCarthy gets a call on the radio. There's a lorry crammed with car tires that's about to board a ferry any second but they suspect it may also have people hiding deep inside. Bridgette's team rush over, and after clambering over hundred of tires they find 7 Indian men. Minutes later there's another call about another lorry ready to board a ferry.

A routine passport control check with Immigration Officer Steve Hassler turns into a marathon investigation. The "student" from Pakistan makes a mess of his answers and Hassler smells a rat. Spanning 2 days, 2 Chief Immigration Officers and a second Immigration Officer, the man, they discover is a taxi driver with a wife and 2 children, living in Luton. He is refused entry to Britain.
