Alex, now a famous TV presenter with his best friend Billy, was once plagued by hallucinations as a child, in which the 'watchers' would peer from the shadows. His medication staves them off these days until he meets the unlikeable American Warwick Vane, who introduces him to the strange organisation of Trinity, based somewhere in the London Underground.Alex and Billy live, breathe and eat football, so when they are given the opportunity to change England's 1966 World Cup defeat by West Germany, they jump at the chance despite the craziness regarding their ability to time travel. They are thrown into a world where time has crossed boundaries and tourists from the future can travel back in time to watch historical events from a benevolent distance. However some powerful people know that events in the past can be manipulated for their own gain, and Billy and Alex find their lives in grave danger.
