Welcome to the guesthouse on the Green, where Mammy and her girls will make you feel part of the family. Settle in and enjoy your stay at O'Mara's, where stories abound, romance lurks and laughter sounds. One of the O'Mara girls is expecting, but who? Mammy O'Mara, upon inadvertently finding out her daughter's pregnant, immediately calls a family conference with disastrous results. At a time when the sisters need each other the most, they're at loggerheads, and for one of them, her future as a single mammy is terrifying. Bronagh Hanrahan, O'Mara's receptionist, wonders why her beau, Leonard, is reluctant to introduce her to his sister, Joan. Her curiosity gets the better of her, and she takes matters into her own hands. Joan, she decides, is a woman desperately in need of help. Sometimes you can't fix what's broken, though. Or can you?
