This week on Customs, it's all hands on deck as officers search a huge cargo ship for illegal goods, the team at the Port check out an army of Welsh rugby fans and in Cork the hunt is on for illegal fuel users. Robbie's anti-evasion unit track illegal fuel users in Cork where a check point targets people using green agricultural diesel in their cars. At Dublin Port, Martin Rogers and his team take on a massive cargo ship in a major search operation. With 62 containers on board the job takes its toll on the search unit, who work long into the night. Dog handler Andrea Leamy and her dog Thatcher put 1200 Welsh rugby fans through their paces as they arrive at Dublin Port, and sniffs out a few suspects. Down in Rosslare, a Officer Dinny Lawlor's dog Dillon gets into a state of distraction but the team persevere.
