After leaping for a while through the countryside, Hulk stops to think how to reach the Niagara Falls, spot newly weds
Glenn Talbot and
Betty Ross chose for their honeymoon (married two issues ago,
Incredible Hulk #158). Hulk wants Betty to be his. Better hide Talbot!
Calm surroundings turn
Hulk into
Bruce Banner who, having some memories left from the man brute, believes Betty to be in danger! Reaching the nearest city, Banner hires pilot
Spad McKraken to take him to the Niagara Falls.
But as he arrives, Banner loses his cool and turns into the Hulk, who jumps out of the plane (leaving a big hole in it), and dives into the falls.

Talbot freaks out to see Hulk there (since the Major believed the green monster was dead or lost in the microverse,
Incredible Hulk #154), and calls
Thunderbolt Ross, who suggests that he take Betty away immediately. Ross sends in his forces to contain Ol' Greenskin.
Coincidentally, amphibious super villain
Tiger Shark hid in the Niagara Falls in fear of the
Sub-Mariner wrath for having killed his father. Believing Namor sent his friend the Hulk, so the Tiger Shark attacks!

After a brief struggle, Hulk knocks his enemy out just as fighter planes were arriving. Not willing to lose any more time, Hulk digs a cave in the rocks to escape from the Air Force, and proceeds with his search for Betty!
