Kiss of Life (2003)

Helen lives in London with her father and her kids. John, her husband, is an aid-worker in Eastern Europe. He has been gone many months. Helen is desperately anxious that he should come home. Taking the kids to school one morning, she is killed in a car accident. She remains caught in limbo, trapped between life and death. Many miles away, in war-torn Eastern Europe, John is unaware that his wife has died. As Helen herself is unaware that she is dead. Thus begins, a four-day Odyssey: Grandpa and the kids must come to terms with Helen's death; John must travel across a war-torn land as he tries to reach home; and Helen must stand helplessly observing her own existence as it comes back to haunt her - until at last she is reconciled with John, and thus released.
