3 Days to Kill is a 2014 action thriller directed by McG and written by Luc Besson and Adi Hasak. The film stars Kevin Costner as Ethan Renner, a veteran CIA agent who is diagnosed with a terminal illness and decides to reconnect with his estranged family before he dies. However, his plans are interrupted when he is offered an experimental drug that could save his life in exchange for one last mission to capture a terrorist called The Wolf.
Ethan reluctantly agrees to the mission and is given three days to track down The Wolf in Paris, where he must also look after his teenage daughter Zooey (Hailee Steinfeld), whom he has not seen in ten years, while his ex-wife Christine (Connie Nielsen) is out of town. Meanwhile, Ethan is constantly plagued by hallucinations and physical side effects from the experimental drug, which further complicates his mission.
As Ethan starts to bond with Zooey, he also learns that she has been bullied at school and gets involved in her life by teaching her how to ride a bike, going shopping together, and helping her with homework. At the same time, he uses his spy skills to track down The Wolf, who is planning a major attack in the city and is hiding in a heavily guarded apartment complex.
As Ethan gets closer to The Wolf, he also uncovers a web of corruption and betrayal within the CIA and must decide whether to complete his mission or risk his life to protect his family. With time running out and his physical condition deteriorating, Ethan must use all his skills and resources to stop The Wolf and save his daughter before it's too late.
Overall, 3 Days to Kill is an engaging and entertaining action thriller that blends suspense, humor, and drama, with some touching moments between a father and his daughter. The film also benefits from Kevin Costner's charismatic performance as a tough but vulnerable spy who is trying to make amends for his past mistakes and reconnect with his family.
