Johnny Frank Garrett (Devin Bonnée) is still protesting his innocence 10 years after being convicted as a teenager of the rape and murder of a Texas nun in 1981.

On the eve of his execution, he leaves a written curse, promising retribution from beyond the grave on the people who condemned him to death.

Inspired by a real-life case (yes, really), this supernatural horror thriller by British-born Simon Rumley goes flashily over the top in places. but creates a genuine mood of dread and delivers some effective scares.
