Carole moves into the cottage in an attempt to come to terms with, not only David's accident, but those revelations of events from years past.
David has survived the accident, if lying in a coma in a hospital bed can be called surviving.
Although David is aware of his surroundings he is unable to communicate with those around him and, with his usual laid-back approach to things, struggles to find a way to overcome the restrictions placed upon him by whichever God had decided to punish him forwhat? Not believing? Not caring? Just, getting on with life?
Huh!
Some life this is!
In your dreams, you can do anything you want to do.
But,
The one thing you cannot do is wake up!
And,
The worst thing with being in the dark is, not being in the light!
