Chazz, the heir to a great fortune, suffers debilitating mood swings that threaten his once-perfect marriage. GianCarlo, a kindhearted young Italian, looks for a way out of the life of thievery he leads with his impoverished and orphaned brothers. Anais feels the insults of old age too acutely when her beloved son marries a woman who seems to despise her. Sophie, a talented young photographer reeling from the sudden death of her family, finds herself vulnerable to the pangs of a lovesick heart. And then there is the accident--if in truth it is an accident--that joins each of these lives to the others in ways both profound and mundane. At the center we find beautiful, bereaved Claudette, wife of the doomed Chazz, taking the eponymous train to Cannes where she, like all the others, remembers her past and draws from it irresolvable feelings of strength and fragility, meaning and emptiness, permanence and loss.
