The microfilm would have revealed the location of the Betratron Bomb, which Hydra will use to ransom the world. Leslie Farrington, chairmanship of Imperial Industries tells his assistant, Brown to track info on every board member, one of which is the Imperial Hydra. In a secret chamber below the boardroom Hydra's leader speaks to "Agent G", his daughter who begs him to end his mad plan, but he replies he is doing it for her benefit. The bomb launches without a hitch...

Part 3 of 7. 1st appearance of the SHIELD Communication Center. The chase sequence, from train to car-turned-submarine vs. frogmen is strikingly similar to the one in the film THE SPY WHO LOVED ME (1977). First modern appearance of Dum Dum & Gabe (regular cast members in SGT. FURY AND HIS HOLWING COMMANDOS). The relationship between Imperial Hydra & Agent G pays tribute to that of Doctor Fu Manchu & Fah Lo Suee, or The Yellow Claw and his niece, Suwan.
