Turning over a new leaf, Ariel buys a flat in the heart of London. Her neighbor Eggsy seems harmless enough, but the more they become closer, the more she doubts he's just a tailor.

In the aftermath of V-day, the Kingsmen have their hands full. New spots open up, old spots are filled, and Eggsy finds himself with a brand new set of problems to deal with. When Merlin finally tells him that Harry Hart hadn't been killed at the church, he doesn't know what to expect, but it isn't what he finds.
