A hooded figure and a twisted old man meet in a darkened room to review tapes of the Avengers in vivid action. The senior conspirator agrees a billion dollar contract with the hood, named the Assassin, to eliminate all of the Avengers.
Captain America is targeted first. In a ploy to strike at the heart of the team, by taking out the head. Cap is gravely wounded and left to die in slow agony.
Avengers en masse, gather at the local hospital to guard their fallen friend. Hawkeye disrupts a follow-up attack at the hospital, but the perpetrators escape. This is just a diversion, and part of a greater plan by the Assassin.
