A dying mother's life lessons to the husband and sons she left behind. Based on the best-selling novel by St John (Singe) Greene, the film is the story of Singe and Kate, a couple from North Somerset, whose lives were turned upside down when Kate was diagnosed with an incurable breast cancer. Over her last few days, she created her list: writing her thoughts and memories down, to help the man she loved create the best life possible for their two sons, after she was gone.

When the unexpected happens, architect Jonathan Rivers has become a grieving widower, wallowing in deep confusion over the death of his wife. But a paranormal expert approaches Jonathan with the unlikely: the ability to hear his wife from beyond the grave. Through a form of unusual communication known as EVP (Electronic Voice Phenomenon), Jonathan will finally be able to see his wife. But in doing so, Jonathan has drawn himself into a much more complex situation when his curiosity becomes an obsession. Only that obsession will have him confront those not of this world, and some of them don't approve of Jonathan's interference with their destructive nature.
