Black Widow has been poisoned by The Hand, and only Daredevil can save her. But Matt Murdock has been placed in isolation under strict orders from Stick; he must face his hyper sensitivity alone, and without distraction. How will Black Widow reach Daredevil? It will all be for naught if the poison kills her first!
The Black Widow was poisoned during the fight with the Hand and has refused help from anyone other than Matt/Daredevil. Matt however is trying to recover his hyper senses in an isolation chamber with the 'help' of Stick and the Ninjas of Chaste.
