Huw Miller (Jason Watkins) has just retired from the local police department. He had experienced a mental breakdown years earlier when he wasn’t able to solve the case of a stalker-killer. That still haunts him to this day.

Then, his neighbor and friend Frank is found dead. The authorities believe it was a suicide, but Huw knows better. Frank would never kill himself. Something is strange about his friend’s death, and Huw wants to delve into this mystery.

Then, immediately after his death Frank’s house goes up for sale and it is bought by Patrick Harbottle (Robson Green), sight unseen. That is a red flag for Huw.

As Huw gets closer to Patrick, things get more tense for him. This new guy just doesn’t add up. He immediately befriends everyone on the block, endearing him to all his neighbors, even Huw’s wife Alice (Sunetra Sarker).

As Huw starts to add up clues unobtrusively left by Patrick, his gut tells him that his new neighbor is the one that got away. The stalker-killer is living right across the street from him, toying with him at every turn.

Huw’s uptight demeanor concerns his wife and when he confides his suspicion, she dismisses it. But Huw will not give up. He has to solve this case if it is the last thing he does. It has been haunting him for years, and now his suspect is taunting him. Haunting and taunting puts Huw in a delicate and difficult state.

How can he convince everyone that Patrick is the stalker-killer? Even his old colleagues in the police department dismiss him. Detective Sergeant Jenny Atkins (Amber James) has a soft spot for her former boss and does not dismiss him as easily as the others. But without evidence, there is nothing she can do.

So Huw takes it upon himself to get Patrick to slip up, or at least find some physical proof that he is the stalker-killer. While doing this, viewers might get frustrated with his methods. As he goes about trying to solve the illusive case, his common sense goes out the window. He leaves his fingerprints wherever he goes. He makes scenes in public. That does not bode well for him when the police are called in.

As this delicate game of cat and mouse plays out over the four episodes, the frustration grows. Everyone around him thinks Huw is having another mental breakdown. But he is perfectly sane, if not emotionally tied up inside.

While the intricate and delicate web is woven by Patrick, Huw is relentless. Patrick is sly, but he has to slip up sometime, or will he get away like he did years ago?
