A young, struggling writer in London adopts the peculiarity of following strangers about the streets to seek inspiration for his craft. Each expedition driven by curiosity leads him deeper into the voyeuristic hobby, prompting him to set ground rules for himself to avoid dangerously obsessive behavior. His fascination reaches a pinnacle when he breaks his own most significant rule by tailing the same person repeatedly. This recurring subject is a well-dressed man who exudes confidence and mystery. The writer's fixation on this individual soon sees him caught in a web he didn't anticipate, shaking the foundations of his once harmless pastime.

The writer's pursuit evolves when he is unexpectedly confronted by the man he has been following, who introduces himself as a professional thief. This encounter spirals into a mentorship where the writer is lured into London's criminal underworld, finding himself swept up in the thrill and complexity of burglary. Each break-in that they commit together unwraps more layers of deceit and personal secrets, thrusting the writer into a reality far from the pages of any story he might have hoped to compose. As he becomes entangled in this lifestyle, the line between observer and participant blurs, pulling the writer into a narrative that spirals beyond his control.
