Sergio Colombo is an insurance agent. He had just gone through a divorce so he is a little bit scattered. Wanting to unwind he plans to go to vacation with a magnificent girlfriend but suddenly he is ordered off to Canada in order to sign an important contract. At the airport Colombo accidentally gets on a plane that flies in a direction directly opposite to Canada - to Bankgok.

If Sergio Colombo, a middle age man, doesn't want to lose his job, has to attend a full immersion English course in UK. So Sergio leave his wife and son and reaches a school full of terrible kids. Obviously he is the only adult and the worse student. Learning English hasn't been never so hard.
