Five lifelong friends reunite to complete a historic pub crawl from their youth, and find that reaching the fabled World's End tavern will be no simple undertaking while they also fight for the future of all mankind. Twenty years ago, Gary King (Simon Pegg) and his pals embarked on the ultimate drinking marathon. But the beer got the best of them, and they failed to drink their final pint at the World's End pub. Now, as die-hard rebel Gary approaches middle age, he summons his old friends back to their hometown for another round. With each pint down, Gary and the gang take another step toward reconciling with the past. Yet just when it starts to look like their goal is in sight, the pals realize that a much larger struggle is currently taking place, and that the future seems particularly grim -- not only for them, but for the entire human race. Nick Frost, Paddy Considine, Martin Freeman, Eddie Marsan, and Rosamund Pike co-star in the final chapter of Edgar Wright's "Three Flavors Cornetto Trilogy," which began with 2004's SHAUN OF THE DEAD and continued in 2007's HOT FUZZ.
