After modifying his armor to go after the submarine with Bethany Cabe aboard, Tony engages Force in underwater combat!
Tony gets Rhodes back to his island and begins to modify his armor. So that, he can track down the submersible vessel carrying Bethany.
Aboard the vessel, Bethany is brought before Justin Hammer who has been capturing yachts to load them with opium to smuggle into the USA. Hammer has made Force chief operative in the endeavor, having renovated the villain's armor since he first fought the Sub-Mariner.
Iron Man manages to locate the craft and battles Force underwater.
In Allentown, Iowa, Nick Fury has begun a S.H.I.E.L.D. investigation into the sudden death of the populace.
Back in the Caribbean Iron Man defeats Force and invades the submersible craft. He wrecks the ship, but Hammer has already launched his fleet of smuggling yachts. Unable to kill Hammer, Iron Man retreats and retrieves Bethany from one of the yachts, returning to the island for the rest of their vacation.
