Céline is fleeing from her despairing and abusive father, while Peter is distancing himself from his homeland of England and the sorrowful memories of his deceased wife and daughter. Over a brief period, with minimal conversation, Céline discovers her first genuine experiences of childhood joy, freedom, and trust. Meanwhile, Peter approaches the final days of his life, offering himself as a kind and aging guardian angel to this troubled child.
