In a rainy and nocturnal London, we follow Miles: a nighthawk, a loner and a voyeuristic photographer. Under the pseudonym 'Rain Catcher', he made a name for himself on social media for his stolen snapshots: morbid and unforgiving portraits of the city's troubled humanity. Soon Miles notices a mysterious woman appearing in his pictures. This shady stalker is following him everywhere, and soon begins sabotaging his life, catapulting him in a Dantesque journey. Every cornerstone of Miles' existence gradually starts to crumble: his online persona, his career, his own life. Aided by his magnetic, gung-ho neighbour Yumi, Miles will embark on a relentless investigation to crack the puzzle leading to his chaser's identity and motive, clue after clue, one snapshot after another, before his world collapses.
