Depth was a comic strip printed in Editorial Mo.Pa.Sa's 'El Planeta De Los Simios' 1977 Argentinian comics, written by Jorge Claudio Morhain and illustrated by Sergio Alejandro Mulko, and featuring the characters from the Planet of the Apes TV series.
Ape slavers blow a conch as they round up a group of primitive humans in a chain-gang. From a tower, Virdon shoots an ape slaver. This frightens the squad leader, Captain Tormo, as the tower is considered taboo. The apes retreat, and the primitives kneel to worship the tower, the only building in the valley to withstand the atomic bombs. Tormo's team returns with permission from Urko to ignore the taboo, and the panicked humans crowd into the crumbling tower. Locating a tunnel door, the fugitives lead them to a subway station, the apes in hot pursuit. The subway is lit by mutated luminous fungus. The primitives run back up the stairs, terrified that the gods are punishing them for violating taboo. Tormo's soldiers recapture all but one of them, who stays with the fugitives. She says her people fear the giant rats living these tunnels, mutated by radiation to human size, who keep blind sub-humans as slaves. The sub-humans attack until Virdon convinces them he's a friend. Stirred by ancient memories, the sub-humans lead them to their masters. The rodent leader reacts angrily to Galen, and several attack, but the sub-humans aid the fugitives, slaughtering their former masters. Touched that Virdon and Burke would risk their lives to help an ape, Tormo fights alongside them. He realizes he misjudged them and lets them go free, promising to protect the sub-humans and to speak to the Council about ending the hunts.
