It’s 1995, and Alex Dean has it all: a spot at Cambridge University next year and the love of an amazing woman. But a brutal encounter with a ghost from his past sees him beaten, battered and almost drowning in the Thames. He wakes the next day to find he’s in a messy, derelict room he’s never seen before, with no idea of how he got there. A glimpse in the mirror tells him he’s older --- much older --- and has been living a hard life, his features ravaged by time and poor decisions. He snatches a newspaper and finds it’s 2010 --- 15 years since the fight. After finally drifting off to sleep, Alex wakes the following morning to find it’s now 2019. But the next day, it’s 1999. Never knowing which day is coming, he begins to piece together what happens in his life after that fateful night by the river. But what exactly is going on?
