1910, Edinburgh. Jessie, the devil's daughter, arrives on the doorstep of an imposing tenement building and knocks on a freshly painted wooden door. She has been sent by her father to bear a child for a wealthy couple, but, when things go wrong, she places a curse on the building and all who live there - and it lasts a century.
Caught in the crossfire are the residents of 10 Luckenbooth Close, and they all have their own stories to tell. While the world outside is changing, inside, the curse creeps up all nine floors and through each door. Soon, the building's longest kept secret - the truth of what happened to Jessie - will finally be heard.
