American Todd Margaret bluffs his way into an apparently great job opportunity, heading up the sales team in his employer's London office. All he has to do is sell several thousand energy drinks before his boss arrives. Simple. Apart from the fact that he knows nothing about British culture and nothing about sales. This is further complicated when he lies continuously to cover his ignorance and spectacularly fails to impress Alice, the first beautiful girl he meets. Dave, his British co-worker, takes full advantage of Todd's situation. Todd's increasingly poor decisions soon land him in big trouble, offending the majority of the British population along the way.
