Plot
Emma leads a double life, Dave's loving wife for seven years and Wyatt and Caroline's mother, but also secretly an assassin. Her frequent “business trips” create a rift in her family life, leading to missed anniversaries and strained attempts to maintain a connection with her loved ones.
Emma's handler Raj calls to update her, trying to tempt her with a high-paying hit. Reminding her to keep a low profile, he has found another ad on the dark web from her former employer Sovereign offering a reward for finding her.
To rekindle their passion, Emma and Dave plan a role-playing game, meeting at a hotel as strangers. It takes a dramatic turn when Emma’s two worlds collide. As she is waiting for Dave, Bob Kitterman introduces himself, having recognised her. Emma continues to use her assumed name, as he repeatedly alludes to their shared profession. Bob mentions his room number and leaves.
The couple continue with their role play and drinking heavily, then head to their room, where Dave promptly falls asleep. Emma sneaks up to Bob's room. Trying to blackmail her, he asks for a sizeable cut of her future hits as his partner. Refusing, citing the 30% she already pays Raj, she reveals she spiked Bob's scotch when they were in the bar. Bob is shortly incapacitated.
Hurrying to their room, Dave apologizes for seemingly falling asleep and they soon head home. Contacting Raj about her blown cover, Emma warns him she's coming to him in Germany. Citing a 6ork emergency in Boise, she flies off to Europe.
On Monday, when Dave goes to collect Emma at the airport, she does not appear and is not registered on the flight. He stays all day in case, and NYPD homicide detectives bring him in for questioning. As they are taking his statement Special Agent Carver from the ITIC enters. She shows Dave that Emma took over the identity of a woman who died 8 years ago, and that she is an assassin.
As soon as Dave arrives home, he finds Emma's passports, guns and other paraphernalia. Carver shows up, asking to come in and look around, so he asks to see a warrant. Meanwhile, Raj picks up Emma at the German airport. He warns her that Sovereign will never let her have a normal life, just as she spots them. Carver gets word that Emma has been found, so leaves Dave.
Emma takes out two Sovereign assassins on foot. Reconnecting with Raj, another shoots at them, inadvertently killing him. Shortly after, Dave calls Raj's mobile and talks with Emma. He insists on coming to Berlin to help her, despite her protests. Upon arriving, Dave sees a driver with the pseudonym he had used in the hotel, and is taken to a small café. There Emma tells him her name used to be Anna. Her father was in the secret service, but later started Sovereign with Carver. When he died, she raised her, training her to be an assassin.
When Emma met Dave in Boston, she fell in love and realised she wanted out. She promises she needs to tie up loose ends, then will stop killing as she simply wants a normal and safe life for them as a family. Four Sovereign employees find and tranquilize them.
Emma wakes in a compound in the forest, hearing her kids. Carver has flown them over, as she convinced Dave's sister Molly to hand them over. She tells Emma she and the kids will be safe once she returns to Sovereign and kills Dave. Taking him for a walk in the woods, Emma has him hold her, so she can whisper that she has to shoot him but promises it won't be fatal. After the gun goes off, he plays dead, then Emma kills the woman who comes to confirm. Next, she takes out the sniper. Back at the compound, Emma takes out another, and sends Dave to watch the kids.
Emma takes out Carver's last mercenary. Taking to the woods, they exchange bullets until Carver goes down. Fatally wounded, she asks Emma to finish her off, but she'd rather let her bleed out. Reuniting with her family, they head out together
