Although she's taken an interest in Irish embroidery, Marcy cannot help but abandon her needlecraft when handsome local brewer Todd finds himself accused of murder. During a St. Patrick's Day party at the pub, a gunshot causes a commotion, leading the police to the back room where Todd and his friend Blake are standing with the body of their former fraternity brother and a smoking gun. Marcy is determined to prove the culprit was someone else, but to do so she'll need to stitch together some luck from more than a few four-leaf clovers.
