This series follows the lives of Irelands' Customs Officers while they work.

With unprecedented access to the daily operations of Ireland's customs officers, we have the opportunity to see, up close, how the country is dealing with the increasing level of importation of illegal materials and substances.

24-hours-a-day, the ten men and women featured in this series work to protect the nation's borders. This is an extraordinary job. The hours are extreme and no day is like another. In a game of cat and mouse they try to out-think the criminals, and sometimes they are successful. They find shipments of drugs in the strangest places: a doll's house; picture frames; the bottom of a massive cargo ship. Large quantities of money, cigarettes and cars are regularly seized, as well as loads of other illegal goods and substances. And then there are the more bizarre finds, like a Colombian snake!

The officers work like a police force, conducting dawn raids, getting involved in car chases, doing stake outs and investigating leads. As the battle intensifies their equipment is upgraded - now including high powered boats to patrol the coast, mobile x-ray trucks and highly sensitive scanners for use in the ports and airports.

These officers witness a fascinating side of Irish life that has remained mostly hidden from the public. They have never been filmed in action before. Until now.
