Synopsis:
While making repairs to one of their planes on a small island, three Blackhawks leave the others to explore the nearby caves. When the three explorers do not return, the remaining Blackhawk begin a search for their friends. Inside the caves, the Blackhawks discover three cavemen wearing Blackhawk caps. The cavemen lead them to a time portal which transports the team back in time.

When they arrive in the past, the Blackhawks send Blackie to scout the area. He locates the missing Blackhawks, who are the captives of a tribe of cavemen. Blackie helps them escape and reunite with the others. The Blackhawks then escape the cavemen, but in doing so the cave containing the time portal collapses. The Blackhawks make it back to their own time, but the portal is now inaccessible.
