Susan Cooper is a desk-bound
CIA employee who remotely assists her partner,
field agent Bradley Fine, on his missions. Fine accidentally kills arms dealer Tihomir Boyanov before Boyanov can tell Fine where a
suitcase nuke is hidden. Susan discovers Boyanov's daughter, Rayna, has contacted terrorist middleman Sergio De Luca, so Fine infiltrates her home. She reveals she knows the identities of the agency's field agents, including Rick Ford and Karen Walker. Rayna then shoots Fine, apparently fatally. Since Susan is an agent but has never been in the field and is therefore unknown to Rayna, she volunteers to track Rayna herself. When Susan's boss, Elaine Crocker, reluctantly agrees, Ford objects due to Susan's inexperience and quits in protest. With her best friend and colleague Nancy providing remote intelligence, Susan goes to
Paris. A rogue Ford shows up, insisting she will fail. Susan discovers De Luca's office has been burned down, but finds a photo of a man standing next to the fire. Ford appears, argues with Susan again and leaves. Susan sees the man from the photo switch Ford's backpack with one containing a bomb. She warns Ford in time, prompting him to throw it into the
Seine, interrupting the nearby
Verka Serduchka concert. Pursuing the man, she accidentally kills him during the ensuing fight. Susan finds proof that De Luca is going to
Rome. Now more determined than ever, she is sent after him. Susan's contact there is Aldo, a lustful Italian who repeatedly flirts with her. Following De Luca into a casino, Susan saves Rayna's life from an assassination attempt in which her drink was
spiked with
acid. Rayna invites Susan into her inner circle, taking her by private jet to
Budapest. In mid-flight, the steward kills Rayna's crew, but Susan subdues him and takes control of the plane. Rayna believes her to be a CIA agent, but Susan convinces Rayna she is a bodyguard who was hired by Rayna's father. Nancy joins Susan in Budapest. After being shot at, Susan pursues and catches the would-be assassin: Karen, who sold Rayna the agents' names. She tries to shoot Susan, but a sniper kills her first. Susan, Nancy and Aldo accompany Rayna to a party to meet Rayna's contact, Lia. Nancy creates a diversion, jumping on performer
50 Cent, so Susan can apprehend Lia, but Ford's inopportune intervention lets her escape. Susan catches her and, during a brutal fight, is saved from death by Fine, who is revealed to have faked his murder and is Rayna's lover and associate. Rayna imprisons Susan and Aldo, but Fine visits them, revealing he is gaining Rayna's trust to locate the nuke, and he was who killed Karen. Susan and Aldo escape, and she follows Fine and Rayna to De Luca's mansion. There, she convinces them that the CIA has mistreated her, and she will do anything to protect Fine, as she loves him.
Terrorist Solsa Dudaev arrives and gives De Luca a suitcase full of diamonds as payment for the device. De Luca has Dudaev and his men killed, revealing his plan to resell the device, then prepares to shoot Rayna. Ford arrives and unintentionally distracts him, allowing Susan to kill his men. De Luca escapes by helicopter with the device and the diamonds, but Susan grabs onto a landing skid. Ford chases after them and grabs onto Susan but falls into the lake. In the ensuing struggle, Susan throws the diamonds and the device into the lake below. De Luca attempts to shoot Susan, but Nancy, following in 50 Cent's helicopter with Aldo piloting, shoots him first. De Luca falls out of the helicopter into the lake. The nuke is retrieved and Rayna is arrested, but she makes peace with Susan. Aldo tells Susan he is actually an MI6 agent named Albert, but he subsequently indicates that he might be lying. Ford realizes he had underestimated Susan and compliments her skills. Crocker officially makes Susan a field agent and gives her another assignment in Prague. Fine invites Susan to dinner, but she opts for a night out with Nancy. The next morning, Susan wakes up in bed next to Ford and screams, while Ford claims she "loved it". ==Cast==
