Jen Kornfeldt travels to
Nice,
France, with her parents after a break-up. She meets Spencer Aimes and agrees to join him later for drinks. He sneaks aboard a boat, planting a bomb on a helicopter, then arrives for his date with Jen. When the helicopter takes off, Spencer triggers the bomb. After a night of drinking, Spencer reveals he is a professional assassin, unaware that Jen has fallen asleep. Despite his boss Holbrook's objections, Spencer quits contract killing and begins a relationship with Jen. He eventually asks her father Mr. Kornfeldt for his blessing to marry her. Three years later, Spencer and Jen have settled into married life. When she surprises him with tickets to Nice for his birthday, he is less than enthusiastic, which Jen's friends convince her is a sign he is bored with their relationship. Spencer receives a "romantic" postcard from Holbrook with an ultimatum to take another assignment. Trying to refuse the job over the phone, Spencer hangs up suddenly when Jen's father arrives, prompting suspicion; he also notices the postcard. Mr. Kornfeldt brings Spencer to a surprise birthday party, where Spencer's distraction over the assignment strengthens Jen's doubts about his commitment. This is further fueled in the morning when he rushes Jen off on her business trip. Jen decides to return home and finds Spencer fighting off his best friend Henry, secretly a fellow assassin, who reveals a $20 million bounty has been placed on Spencer and that anyone in his life could be an assassin. A sniper opens fire on the house, and Spencer and Jen flee. They lead Henry on a car chase through the neighborhood and flip his car onto rebar, killing him. After the couple find Holbrook dead in his hotel room, Jen vomits and realizes she might be pregnant. At Spencer's office, she takes a pregnancy test, while he is attacked by his secretary, Vivian. But Spencer, with Jen's help, manages to kill her. Jen's test is positive, and despite Spencer's pleas, she drives off alone. Spencer is attacked by a delivery driver, who is run over and killed by one of Spencer's co-workers, Olivia. She then tries to run him over, but Jen returns and rams Olivia's car into a fuel tank, which Spencer shoots. The car explodes, killing Olivia in the process. Spencer and Jen discuss their future together and return home, evading next door neighbors Mac and Lily, who are also assassins. Making their way through the neighbourhood
block party, they enter the house to retrieve Spencer's
bug-out bag. Spencer subdues the neighbours, while Jen's best friend Kristen, yet another assassin, holds Jen's mother hostage in a
Mexican standoff with Jen. Jen's father arrives and kills Kristen. In a standoff with Spencer, he reveals that he ordered the hit. Aware of Spencer's career all along, Mr. Kornfeldt explains that he was a former operative himself and had been Spencer's target in Nice; he embedded the assassins in Spencer and Jen's lives. The postcard from Holbrook led Mr. Kornfeldt to believe that Spencer had resumed his old job, so he
activated the assassins. To prove he has truly left his old profession behind, Spencer drops his gun, assuring Mr. Kornfeldt he has no intention of killing him. Jen, now convinced, reveals her pregnancy to her parents. Her father, after killing one last assassin, drops his gun as well, and the family makes peace by building a trust circle. Months later, Spencer – growing a moustache to emulate Mr. Kornfeldt – and Jen leave her parents babysitting their baby boy, guarded by lasers. ==Cast==
