New York firefighter Patrick Sullivan had no idea his seemingly idyllic life was about to go up in smoke - especially as the unwitting, second-hand recipient of advice from famed love expert and radio host Dr. Emma Lloyd. But when Patrick and his computer-savvy neighbor decide to give Dr. Lloyd a taste of her own medicine and “accidentally” join them in holy matrimony - something that doesn’t go over too well with her fiancee (played by Colin Firth) — it isn’t long before they learn that sometimes even an expert in love needs a second opinion.
