In a London apartment, two young boys grieve their mother's sudden death. Their scholarly father, a scruffy romantic, envisions a future of well-meaning visitors and loneliness. During this time of despair they encounter Crow who antagonizes them, tricks them, heals them, and watches over them. The sentimental bird draws nearer to the grieving family and threatens to stay until they no longer need him. As weeks turn to months and their pain eventually lessens, the family finally begins to heal.
