Passenger experience manager Demi deals with some disgruntled passengers, while check-in attendants Carrie-Anne and Selina tackle broken baggage belts. Elsewhere, Border force worker Bob has to decide whether he should let a young Brazilian student into the UK to visit his brother.

The King and Queen of Terminal Two, Demi and Sue, wrestle with a bare chested drunk, and back at immigration Kat and Bob come across a visitor whose reason for entering the UK does not add up.

The airport is busy as it is half term with rich Russian kids returning home from British boarding schools, and trouble arrives when the biggest mobile crane stops in the middle of a live airfield.

It is all things Eastern with the arrival of some special cargo, a potential people trafficker flagged to Border Force, and the polar vortex that battered Britain in March affectionately called the Beast from the East. Also, rookie Ian is back.

The Border Force pull over a Ghanaian businessman declaring £114,000 in cash, there is love in the air at the unlikely location of T5 arrivals when a blind date takes place and it is the end of an era on the airfield for chief trainer Simon.

Terminal 5 receives a very special visitor, leaving Buggy Driver Carlo starstruck. British Airways have a new robot on the airfield and Border Force release the hounds in search of dirty money. Last in the series.
