In a London flat, two young boys face the unbearable sadness of their mother's sudden death. Their father, a Ted Hughes scholar and scruffy romantic, imagines a future of well-meaning visitors and emptiness.

In this moment of despair they are visited by Crow - antagonist, trickster, healer, babysitter. This sentimental bird is drawn to the grieving family and threatens to stay until they no longer need him.
