After a young girl witnesses her father having an affair, she declares she will never love anybody ever again. As a result, her guardian angel is forced to abandon her. Later, when she grows to be a miserable woman, her angel is given a second chance to save her from a life of sadness. To accomplish his goal, he travels through time to recruit the woman's past and future selves to help her reconcile with her father and change her direction in life.

Nine year old Molly and her father move to Ireland into a house they've inherited, nicknamed "Misfortune Manor". It brings bad luck to anyone who lives in it, and Molly and her father soon fall victim to the curse: they will lose their new found home unless they can pay the taxes they owe on it. Lucky the Leprechaun is on hand to help Molly break the curse and help with pots of gold.
