Kingsman: The Secret Service (2015)

During a mission in the Middle East in 1997, probationary secret agent Lee Unwin sacrifices himself to protect his superior, Harry Hart, from an explosion. Hart, blaming himself for Lee’s death, returns to London to give Lee’s widow, Michelle, and her young son Gary “Eggsy” a medal engraved with an emergency assistance number. Seventeen years later, Eggsy is a stereotypical chav, having dropped out of training for the Royal Marines despite his intelligence and talents for both gymnastics and parkour. After getting arrested for stealing a car, Eggsy calls the number. Hart arranges his release and explains that he is a member of Kingsman, a private intelligence service founded by British elite who lost their heirs in World War I and put their money towards protecting the world; the organization is named for the tailor shop that clothed them in Savile Row, which they now use as a front for their bases.

Hart, code name “Galahad”, explains there is a position available, as agent “Lancelot” was killed by the assassin Gazelle while trying to rescue university professor James Arnold from kidnappers. Eggsy becomes Hart’s candidate. Kingsman’s technical support operative “Merlin” discovers that Professor Arnold is working as though nothing has happened. Hart attempts to interrogate him at Imperial College London, but a microchip in Professor Arnold’s neck explodes, killing him. The detonation signal is traced to a facility owned by Gazelle’s employer Richmond Valentine, an Internet billionaire and philanthropist who has offered everyone in the world SIM cards that grant free cellular and Internet connectivity. Hart, impersonating as a billionaire philanthropist, meets Valentine face to face.
