Planning a wedding is hard enough without international politics, an assassin, your fiancé's ex-boyfriend and your mother to deal with. NYPD Detective Frank Schultt and his fiancé, FBI Agent Aaron Massey, have bought a new condo, adopted a dog and are planning their wedding. But when an international assassin starts killing people on the streets of New York City, Aaron and Frank must work together to find the killer before she strikes again. Combine the assassin with the pressure of Frank's jealousy when Aaron's ex-boyfriend comes back to town, and can their relationship withstand the pressure? Will Aaron and Frank make it to the altar on time, or will the assassin and Frank's destructive behavior stop their wedding before it ever heads down the aisle?
