An American master chemist plans to score big on a once in a lifetime drug deal. All does not go as planned and he is soon entangled in a web of deceit.

Elmo McElroy is a streetwise American master chemist who heads to England to sell his special new formula - a powerful, blue concoction guaranteed to take you to 'the 51st state.' McElroy's new product delivers a feeling 51 times more powerful than any thrill, any pleasure, any high in history. But his plans for a quick, profitable score go comically awry when he gets stuck in Liverpool with an unlikely escort and his ex-girlfriend and becomes entangled in a bizarre web of double-dealing and double-crosses.
