In this two-part special to kick of the fourth series, the Teutuls leave the US for the first time and set out on an international road trip.

Paul Senior, Junior and Mikey embark on a sightseeing extravaganza visiting London, Edinburgh, Normandy, Paris, Stonehenge and the Ring of Kerry. The boys start to worry about Paul Senior's fascination with the London Dungeon's torture machines but it's laughter all the way when they hit Scotland and swap their usual jeans and t-shirt for kilts. Once in France the Teutuls try to get to grips with French cuisine and find the people 'real snobby'.

Safely back in the UK they meet up with their old pal Ewan McGregor for a bike ride through the English countryside before ending their unforgettable trip on a high at the famous London to Brighton Burn where they lead thousands of fans on a wild journey.

Back home, it's business as usual at the Orange County Choppers workshop. Family tensions run high and there are plenty of fiery clashes as the Teutuls struggle to meet seemingly impossible deadlines for building their outrageous choppers including a Space Shuttle tribute bike; fantasy bikes for four lucky competition winners and a bike dedicated to the Make A Wish Foundation.

The Teutul's European adventure is packed full of humour, drama and above all chopper bike masterpieces. Don't miss it!
