After wrapping up the Zodiac story from Daredevil 73, Tony Stark decides to live a little. He heads out on the town with flame Marianne Rodgers (her first appearance!) only to find himself at ground zero of an alien invasion in the form of the charmingly philosophical robot harbinger of doom, Ramrod!
