In the Savage Land, Ka-Zar hunts and kills a marauding dinosaur.
He then encounters a bunch of armed invaders and he and Zabu drive them off but
not before one secretly drops a homing device into a river….
In San Francisco, the police try to talk down the Hulk who
is atop one of the towers od f the Golden Gate Bridge with a little girl who
has befriended him. Police Captain Taggart walks up a cable to talk to Hulk
calmly. Hulk does not trust Taggart’s assurance that they will not try to harm
him but the girl asks Hulk to let her go down with Taggart. But Taggart slips
and Hulk lunges to steady him, which the police sharpshooters interpret as an
act of aggression and open fire. Enraged, Hulk jumps through the bridge to land
in the water and swims away. Hulk comes up near a dock where he sits peacefully
and transforms back to Bruce Banner. Bruce goes to the Salvation Army for free
clothing and meals. A sailor who has decided to retire offers Bruce the papers he
needs to ship out. He joins the crew of a tramp steamer and does manual labor
and learns there is a part of the ship where the crew is forbidden to go. A
fellow crewman, Scott, points out the Bruce that the ship is heading south, not
west as they were told. They break into the forbidden area and discover
advanced military craft and munitions. They also encounter the group’s
chairman, MODOK. Bruce and Scott are overpowered and imprisoned; MODOK has
recognized Bruce Banner and orders him sedated. The ship sheds its disguise,
revealing a sleek craft which heads to the Savage Land….
MODOK and his gang arrive in the Savage Land and they spray
somna-gas to put the wildlife to sleep. Ka-Zar gets wind of this and dashes to
the scene and takes on the guards but the gas soon subdues him and Zabu….
He awakens to discover that the dinosaurs are being loaded
onto the ship; MODOK’s scheme is to use the process that mutated him to create
an army of monsters to conquer the world. But the situation so scares Bruce
Banner that, despite the sedatives, he transforms into the Hulk and goes
berserk. Ka-Zar wraps his chains around Hulk’s neck so that the behemoth snaps
them. Ka-Zar then persuades Hulk that the dinosaurs are the enemy. Jade Jaws
fights his way through them and takes on MODOK who employs his mental blasts.
But Hulk keeps bouncing back from the blasts until Zabu leaps on the villain.
Ka-Zar calls him off….
Epilogue: The bad guys are drugged with their own somna-gas
and held for the authorities. Ka-Zar offers Hulk sanctuary in the Savage Land
but Hulk declines and leaps away….
