An ancient bridge collapses over a gorge in Peru, hurling five people into the abyss. It seems a meaningless human tragedy. But one witness, a Franciscan monk, believes the deaths might not be as random as they appear.

There must be a purpose behind their deaths. But are their lost lives the result of sin? ...Or of love?
