Synopsis for "A Duel of Iron!"
Following information from Angar the Screamer (who escaped during interrogation), Iron Fist infiltrates Stark Enterprises to look for the captured Colleen Wing. There he runs into and teams up with Misty Knight who is also investigating Stark to save Colleen, who is her partner in their detective agency Nightwing Restorations.
Elsewhere, Tony Stark is awoken when the intruder alarm goes off and decides to investigate the situation as Iron Man. While Iron Man and Iron Fist duke it out, Colleen is taken to the airport by her captors, led by Donald Cauley. Her attempt to escape fails. Meanwhile Misty finds out that Colleen is being taken to Halwan. Collen stops Iron Man and Iron Fist and reveals that Stark had nothing to do with the kidnapping but sleeper agents were behind the scheme and that they are headed for Halwan. Iron Man wishes Iron Fist the best of luck as he cannot go with them due to prior engagements, Iron Fist and Misty then leave in a jet to find their friend.
