Plot Summary
The Avengers are stunned to discover that their one time ally, Black Widow has chosen to steal classified submarine plans and once again defect behind the Bamboo Curtain. Little do they know that Widow is in fact working for Nick Fury as part of an undercover operation. Meanwhile, Hercules looks for ways to blow off some steam while he adapts to the reality of his banishment. As Hawkeye attempts to clear his mind, he accidentally stumbles into an ambush carefully planned by the Mad Thinker and executed by his allies, the Triumvirate of Terror. Soon Wasp, Goliath, Scarlet Witch and Quicksilver have all fallen victim to similar attacks. Only the timely arrival of Hercules is able to throw a wrench in the Mad Thinker’s plans and the Lion of Olympus makes quick work of the Triumvirate. With the Avengers freed, the Mad Thinker is forced to flee and once again recalculate his plans, only this time he will be sure to account for the presence of an immortal.
