Time flies, and in a blink of an eye, Eggsy (Taron Egerton) has grown into an excellent and reliable agent. The relationship between him and Princess Tilde (Hanna Alström) is getting stronger and stronger, and the two are about to join hands in marriage. At this juncture, former agent Charlie (Edward Holcroft) came back. Now he works for a drug trafficking organization called "Golden Circle". The leader of the organization, Bobby (Julianne Moore), is an evil and ambitious woman. Charlie found all the bases of Kingsman and destroyed them all with missiles. The surviving Eggsy and Merlin (Mark Strong) traveled all the way to the United States to seek help from the federal agents lurking there. Bobby planted a kind of marijuana containing toxins and shipped them to all parts of the world. When the toxins in the addicts' bodies gradually took effect, Bobby used this as a bargaining chip and officially declared war on the government.
