Kingsman: The Secret Service 电影

During a raid in the Middle East in 1997, a probationary secret agent sacrifices himself to save his team. Feeling guilt over the loss of his comrade, Harry Hart, code-named "Galahad," personally delivers a bravery medal to the agent's widow, Michelle Unwin, and his young son, Gary "Eggsy", saying that if they ever need help, they should call the phone number on the back of the medal and deliver a coded message.

Seventeen years later, Professor James Arnold is kidnapped by unknown assailants, led by Internet billionaire Richmond Valentine and his henchwoman Gazelle. One of Hart's compatriots, "Lancelot," attempts to stage a rescue, but fails. Valentine, known for his philanthropy, continues to meet with various heads of state and VIPs; some of whom go missing afterwards. He also announces a giveaway of SIM cards, granting free cellular and Internet access.

In London, Eggsy is now an unemployed young adult living with his mother, infant half-sister, and abusive stepfather Dean. Despite being intelligent and capable, he left training for the Royal Marines and lives an aimless life. After being arrested for stealing a car and taking it for a joyride, Eggsy calls the number on the back of the medal. Hart arranges for his release and tells Eggsy about the existence of Kingsman, a secret intelligence agency for which both he and Eggsy's late father worked. In the wake of Lancelot's death, the agency opens a vacancy for a new agent, and Eggsy agrees to apply. He joins a group of other candidates, including a woman named Roxy. Training is overseen by "Merlin," a senior Kingsman. The candidates are eliminated one by one until Eggsy and Roxy emerge as the final two. However, Eggsy fails his final test, and Roxy becomes the new Lancelot.

During this time, Kingsman have been investigating Valentine in connection with the VIP disappearances and notes that Arnold is no longer missing. Hart tracks down Arnold and confronts him about his abduction. A chip implanted in Arnold's head explodes, killing him; Hart is injured during his escape from unknown assailants. Undeterred, Hart poses as a billionaire and dines with Valentine to try to discern his plans.

Hart tracks Valentine to an obscure hate group church in Kentucky, where Valentine and Gazelle are conducting a test. They broadcast a signal to his SIM cards, causing everyone in the church, including Hart, to become uncontrollably violent. A mass brawl breaks out, with Hart the sole survivor, while Eggsy, Merlin and Arthur—the Kingsman's leader—watch via video link. Valentine approaches him, and they discuss his plan: to broadcast the signal worldwide, using his satellite network to cause a massive culling of the human race. Only a select few that Valentine has deemed worthy of living—those who have sided with him and thus received the protective microchips in their head, and the VIPs he kidnapped—will be spared. Having revealed his plan, Valentine kills Hart.

Eggsy returns to the Kingsman headquarters, where he discovers that Arthur is one of Valentine’s converts. Arthur explains Valentine's views: humanity is akin to a virus, global warming is the Earth's equivalent of a fever, and Valentine intends to do something about the problem before the virus kills the host. After avoiding Arthur’s attempt to kill him—killing the group leader as he does so—Eggsy teams up with Roxy and Merlin. Roxy pilots a high-altitude balloon vehicle into the stratosphere to disrupt Valentine's satellite network with a missile, while Eggsy and Merlin directly assault Valentine’s mountain bunker. Roxy knocks out the satellite and Eggsy fights his way through Valentine’s security forces, while Merlin detonates the security chips, killing all who were part of Valentine's plan. Eggsy then fights and defeats Gazelle before killing Valentine and saving the world. In a mid-credits scene, Eggsy, now a full Kingsman, reaches out to his mother, offering her a nicer house and a chance to get away from Dean.

“金士曼”表面上是英国伦敦萨佛街上的一家裁缝店，天天为客户量身打造帅气的西服，实际上却是一个历史渊源久远的民间谍报组织，以世界和平为宗旨，曾经多次打击了严重犯罪，却极为低调，不欲人知。但他们的能力却不亚于英国秘密情报局（俗称军情六处，MI6）、美国中央情报局（CIA）、俄国对外情报局（FIS，原为KGB第一总局）、以色列情报特工局（MOSSAD）等知名的国家情治单位，

1997年“金士曼”的一群探员潜入位于中东的恐怖组织巢穴，顺利逮捕其首脑，特工哈里·哈特（代号加拉哈德）审问首脑时，却因一时失误没发现首脑想用手榴弹同归于尽，导致一名探员用肉身阻挡而英勇牺牲，虽然救了其他人，但也让哈特感到十分愧疚。

事隔不久，哈特给了已故探员的家属一个“金士曼”徽章，并表明只要打后面的电话号码，并对接线生说出“牛津鞋不是雕花鞋（Oxford Not Brogues）”的暗号，就可以完成任何事。

17年后，一位环境科学教授亚诺遭慈善家里奇蒙·瓦伦丁绑架，一名代号为兰斯洛特的“金士曼”特工前往解救，却被绑架者的手下嘉泽勒杀害。对此，“金士曼”的领导人切斯特（代号亚瑟），要哈特等探员每人推荐一名候选人，并从中挑选一人成为新的“兰斯洛特”，同时亚瑟也命令哈特负责调查兰斯洛特被杀的事件。

另一方面，当年已故探员的儿子埃格西，他母亲的新欢是一个帮派老大，对她动辄施暴，且又生下一个小女孩，埃格西害怕母亲与异父同母的妹妹受害，放弃了成为英国海军陆战队优秀射手与参加奥运体操比赛的机会，成为一名街头混混，留在家中保护母亲。一次为了与继父手下喽啰发生争执，盗车狂飙，又不慎冲撞了警车，被捕入警局，在警官严厉的审讯中，他想起当年拿到的徽章，便拨打徽章后面的电话，警方立刻将他释放。

当埃格西从警局出来时遇见了保释他出来的哈特，两人便到酒吧聊天。哈特告诉埃格西，如果埃格西的生父还在，一定会对埃格西的堕落感到不满，而埃格西反击，含着银汤匙出生的门阀子弟，无法体会他的遭遇。这时埃格西继父的喽啰们出现在酒吧，准备围殴埃格西，他们逼迫哈特离开，哈特同意，谁知他们却出言羞辱了哈特，哈特展现了高超的格斗技巧，只身痛殴了所有喽啰，然后哈特消除了酒保的记忆，也准备把埃格西消除记忆，但是埃格西恳求哈特，发誓绝不会泄漏这件事，因此哈特离开了，虽然离开前在埃格西身上动了手脚。

埃格西回家后，被继父用菜刀威胁，要他供出在酒吧动手的是谁，但埃格西谨守和哈特的诺言，抵死不从。就在埃格西即将被继父攻击时，哈特通过藏在埃格西背上的窃听器与麦克风，确认埃格西守口如瓶，哈特又透过麦克风警告，不许殴打埃格西。埃格西出门后，遇到继父手下喽啰的包围，以跑酷方式逃出，并遵循哈特的指示前往“金士曼”裁缝店，并跟着哈特经由藏在裁缝店地底下的通道前往“金士曼”的总部。哈特告诉埃格西，他推派埃格西接受成为新一任“兰斯洛特”的考验。哈特在埃格西接受考验时，去找了遭到绑架的亚诺教授问话，问到一半教授头部爆炸身亡，哈特虽被炸伤，但也发现幕后藏镜人其实是瓦伦丁。

埃格西接受哈特严厉的指导以及经历了许多艰困测试后，武艺与智慧都大有增进，虽然过程中，不断被其他人嘲笑出身与学历，但还是以智慧与毅力撑到最后两强，忠诚考核也及格，他与另一名女子萝西待到最后，但埃格西却慈悲心作祟，因为不愿杀掉自己一手训练的狗而遭到淘汰，萝西成为了新一任“兰斯洛特”。埃格西失望地偷了亚瑟的汽车回到老家，见到母亲被家暴的伤势后原本想找继父算账，哈特却及时遥控了汽车，将埃格西载到自己家，并要求埃格西闭门思过。

哈特收到线报，前往美国一所充满性别歧视、种族歧视、宗教歧视而被联邦调查局盯上的教堂，准备缉捕瓦伦丁，其实这是瓦伦丁的阴谋，老早就等著哈特上钩，瓦伦丁已用他所制作的SIM卡控制了那教堂，只要瓦伦丁操作仪器，教堂内持有SIM卡者会攻击周围的人，直到对方死亡为止，哈特去了以后，瓦伦丁引爆了教堂激战，哈特与教徒们互相残杀到最后，只剩武艺高强的哈特一个人生还，杀了无数平民的哈特，充满悔恨，走出教堂，却被瓦伦丁枪杀，“金士曼”的总部及埃格西都透过电脑目击全部过程。

已经身怀绝技的埃格西打算为哈特报仇，回到“金士曼”的总部求助，见到“金士曼”的领导者亚瑟，埃格西看出了亚瑟已经变节，投靠瓦伦丁。亚瑟请埃格西饮酒，想要毒死埃格西，埃格西假装没发觉，却来了个移形换影，让亚瑟喝下他自己准备的那杯毒酒，亚瑟毒死自己后，埃格西从亚瑟的身体拔出特殊芯片并交给“金士曼”的幕后要员梅林分析，得知了瓦伦丁的所有计划。

瓦伦丁自比为《旧约》里的上帝，他认为人口太多，造成众多环境污染，为了环保，就要大规模屠杀人类。他利用人类贪小便宜的心理，宣称愿意免费发送给地球上每一个人一张SIM卡，只要在手机插入SIM卡就可以免费上网与拨打电话，一想到再也不用缴电话费与网络费，众人趋之若鹜，全球都爆发了排队请领的风潮。但其实，这张SIM卡发送了诡异的电磁波，会在瓦伦丁下指令后，逼着人们互相残杀。但瓦伦丁有意留下一些人类，将他们比为诺亚方舟：创世之旅。他用协商或者绑架的方式，从世界各地带走富豪与权贵，同意自己计划的人，就必须加入，但瓦伦丁在那些人身上植入了特殊芯片，可以随时引爆，来防止消息外漏；异议分子就囚禁到答应为止。

梅林指派萝西去破坏瓦伦丁的卫星，并要求埃格西潜入瓦伦丁的总部，希望阻止计划。埃格西潜入总部并经历一番激战，协助梅林骇进了瓦伦丁总部，萝西也成功破坏了瓦伦丁的卫星，因此暂时阻止了计划进行，但瓦伦丁神通广大，借到了另一个卫星来支援，因此埃格西只好再回去阻止瓦伦丁，但敌人明显增加许多，在走投无路的情况下，埃格西要求梅林把所有瓦伦丁的手下脑中的特殊芯片引爆，千钧一发之际，埃格西获救，而瓦伦丁的手下以及支持他的富豪权贵们也全部死亡。埃格西此时也发现身后竟是瓦伦丁囚禁瑞典公主提儿蒂的牢房，公主更向他允诺，只要他能拯救世界就跟他做爱。

瓦伦丁愤怒之余，干脆继续执行计划，让全世界的人们开始互相残杀，埃格西必须在SIM卡未完全启动前阻止瓦伦丁，埃格西在与嘉泽勒的一番苦战后，用了鞋尖的特制毒刀刃刺伤了她，打败了她义肢上的刀刃，并在埃格西的母亲即将杀害亲生女儿前，把已死的嘉泽勒义肢上的特殊刀刃如标枪般投掷，刺死了瓦伦丁，全球人们的暴力倾向立刻消失，不再斗殴。埃格西在离开瓦伦丁基地前，先去地牢找提儿蒂公主“兑现支票”。

埃格西终于成为了真正的“金士曼”特工，他向母亲表示自己已经受雇于一家特殊的“裁缝店”，拥有优渥的薪水与豪华宿舍，想要接母共赴新居，从此可以尽一份孝心。但继父拒绝让埃格西把母亲带走，埃格西就如当初哈特收拾他继父的喽啰们一样，在相同的地方，说出相同的名言，作出相同的攻击，把他们好好修理一顿。
