Time fractures. Two lives collide.

On a train journey, two strangers, Susie and Ryan, strike up a conversation. Soon afterwards, a mysterious jolt shakes the carriage and both of them black out. When they wake up, it’s still the same train—but somehow, twelve months have passed.

When Susie returns home, she finds evidence of a man sharing her flat and her bed. Ryan, just as bewildered, turns up at her door to discover he’s now her live-in lover. Susie’s friends and family have welcomed Ryan into their lives. The problem is, neither of them remembers falling in love.

As Susie and Ryan grow closer, they must ask themselves: what exactly happened to them on the train? Where have they been for the last twelve months? And if the Jolt brought them together, could it just as easily take everything away again?

Join Susie and Ryan on a journey through time, where every decision reveals a deeper mystery, and every moment challenges what they thought they knew—about their past, their future, and each other.
