Irishwoman Maureen, who lives in Germany, is happily married. Or so she thinks. When her husband dies, she finds out that not only had he debts, he was also a bigamist who had a second wife and family in Ireland. Shocked and angry, she travels there to meet the other family--and learns that they have their own troubles, the worst being that the other woman's young son is suffering from leukemia and urgently needs a suitable bone-marrow donor.
