Mrs. Muldoon wants to return home to Ireland after living many years in Boston, Massachusetts. She desires to be cured spiritually before embarking on her journey. Molly, a senior in high school, and her Nonna want to help fulfill her wish. They bring her to a faith healer Mrs. Muldoon has heard about in a seedy section of downtown Boston, as well as to the ocean on the Feast of the Assumption for a blessing in the water that day. Will Mrs. Muldoon's prayer for home be answered?
