After her husband Adam is killed when his private boat explodes, Nell McDermot is thrown into a pit of grief. She wants answers and she wants more than anything to say goodbye - but both now seem impossible. That is, until a medium contacts her claiming to be Adam's channel.

When the investigation proves the explosion was not an accident but a bomb, Nell goes to visit the medium. And, soon enough, she is receiving instructions from Adam from beyond the grave. Or is she?

Haunted by grief, Nell undertakes the instructions - unaware that a terrifying chain of events is about to be unleashed. With a dangerous loop closing around her, Nell doesn't realise that she might be going to meet Adam a lot sooner than she thinks . . .
