The Heights is a tall, slender apartment building among warehouses in London. Its roof terrace is so discreet, you wouldn’t know it existed if you weren’t standing at the window of the flat directly opposite. But you are. And that’s when you see a man up there --- a man you’d recognize anywhere. He may be older now, but it’s definitely him. But that can’t be because he’s been dead for over two years. You know this for a fact. Because you’re the one who killed him.

But when Darren and Jodie move into the house on the corner, they donʼt follow the rules. They blast music at all hours, begin an unsightly renovation, and run a used-car business from their yard. It doesn’t take long for an all-out war to start brewing. Then, early one Saturday, a horrific death shocks the street. As police search for witnesses, accusations start flying --- and everyone has something to hide.
