In the 17th-century village of Eyam, two sinners – Colette and Finlay – confront the danger of their pre-marital pregnancy in their parish town. As the black death descends on their village, all sinners are persecuted in a desperate attempt to cleanse Eyam of the plague.

Harbouring a now lethal secret, Colette and Finlay must make a fateful choice: flee the quarantined town in a daring escape, risking isolation and rejection from neighbouring civilisations, or stay and confront the weight of their forbidden love and the deadly consequences it might bring.
