In 1980, three schoolgirls visit St. Valentine's shrine in Dublin, to write their petitions for love. By 2010, these same women have discovered that finding love was the easy part - it's what you do with it once you've found it that's tricky.
When one of the women returns home unexpectedly from California, all three are forced to examine their choices, loves, and lives, which have proved surprising, and in some ways, precarious. So much for St. Valentine - if the saint has taught them anything about love - it's be careful what you wish for . . .
But real love is always a work in progress - and Vonnie, Abby and Diana must learn they need to open their eyes and more especially their hearts - because St. Valentine has some unfinished business with them . . .
