Criminals, including the Russian mafia, Yakuza, and Chinese mob, have taken advantage of Hell's Kitchen's circumstances since the incident of Avengers (2012). Blinded as a boy in an accident that gave him heightened senses, Matt Murdock begins fighting this rising criminal element by night as a costumed vigilante while opening a law firm with his friend, Foggy Nelson.
Their first client is Karen Page, a secretary for construction company Union Allied, who has been framed for the murder of her co-worker, Daniel Fisher, after accidentally uncovering a pension embezzlement scheme.
Murdock prevents Karen from being prosecuted and protects her from an assassin, before exposing the scandal through Ben Urich at The New York Bulletin. Grateful for their help, Page offers to work for Murdock and Nelson.
James Wesley covers up the involvement of his employer in the scandal, and orders Anatoly and Vladimir Ranskahov, the Russians' leaders, to deal with Murdock. They kidnap a young boy to lure him into a trap.
