No self-respecting actor would be seen on a fan cruise... unless he was a true star

Andy Van Allen (Rob Brydon), the former hero of a cult 1980s futuristic TV show, Children of Castor, is now working as an hotel porter. In contrast, his ex co-star, Nick Lee (Steve Coogan), has since shot to fame in the USA starring in a blockbuster mini-series, Sherlock Holmes in Miami. Things start to look up for Andy when an unusual offer comes along - the Children of Castor fan club has organised a cruise around the Greek islands from Istanbul to Athens and invite him to attend as the principal celebrity. Once aboard however, a combination of Andy's cynicism, his fans' adoration, a misguided sexual encounter and an unexpected death ensure the paradise cruise is far from plain sailing. With his world spinning out of control it's time for Andy to pull off the ultimate act which justifies the adoration of his fans - it's time for Andy Van Allen to become a true hero.
