Late one night, two brothers learn that their sister has died in the worst way imaginable. She's found, strangled, in a desolate place hundreds of miles from their East London home. Ruben is the smarter of the two, with a gift for getting into other people's hearts; Cole may be older, but he's a devil's angel who doesn't care if he lives or dies. Together, they set out to find their own answers and retrace Rachel's final journey.
