This movie traces the origins of Mitch Rapp, a character that was featured in more than a dozen books written by late author Vince Flynn. We are introduced to Mitch (O'Brien), a young man enjoying the happiest day of his life on a beach in Ibiza together with his girlfriend Katrina (Charlotte Vega), who just said yes to his marriage proposal. Moments later, a group of gunmen arrive and start shooting. Mitch is badly injured, and watches helplessly as Katrina is killed. About two years later, we see an overzealous Mitch turning himself into a killing machine by taking up martial arts, and learning to shoot a gun with deadly precision. He also tries to make contact with the leader of the terrorist group behind Katrina's murder, which brings him to the attention of the CIA's counter-terrorism chief Irene Kennedy (Sanaa Lathan). Mitch succeeds in making contact, but the terrorists are suspicious of him. While he is being questioned, the CIA swoops in and kills the terrorists, leaving an angry Mitch stabbing at a corpse. Back in the US, Irene offers Mitch an opportunity to put his skills and anger to good use, by sending him to train under CIA trainer Stan Hurley (Keaton), a gruff ex-Navy Seal who doesn't think Mitch is suitable to be an agent. While Stan is determined to send the new recruit packing, circumstances force him to take Mitch, along with another trainee, to meet up with Turkish agent Annika (Shiva Negar) to locate the person building a nuclear bomb. In a news footage, Stan spots someone nicknamed Ghost (Kitsch), who makes off with items needed to make a nuclear bomb, and who is willing to kill anyone who stands in his way. And Ghost always seems to know their next move. On paper, this may seem like a run-off-the-mill spy thriller, but it is the subtle details in how Mitch handles a dangerous situation, and Stan's pragmatic (and somewhat cold) approach to their job, that makes this story stand out. Overall, a good film if you like action thrillers.
