It's now three years later (5 years before Taylor) and Dr. Milo, convinced the world is going to end because of long term ramifications from the moon's destruction (how would that work?), goes into the forbidden zone hoping to find solutions written by the great ancestors (the ancient humans, but he doesn't know that), he accidentally discovers the mutant humans living below ground (that was convenient), is made to be their prisoner and tortured for five years, is finally rescued by a sympathetic human who wants to prevent world destruction, he gets back to Ape City, but Zaius isn't interested, and Ursus tries to kill him for knowing the truth about him (but friends conveniently walk by at just the right moment, so Ursus just kind of forgets about it -- what????), Milo learns about Taylor (who is now gone) and goes looking for his ship to see if it can get people off the planet before it is destroyed, he dredges it up and repairs it (how convenient that he knows how! And so quickly!) and the convenient sympathetic mutant once again moves the plot forward by psychically sending Zira, Cornelius, and Lucius to his aid, they take off as the war between Apes and Mutants begins, Lucius is killed, and we get to the beginning of the third film, with Milo, Zira, and Cornelius arriving on the beach.
