The video shows four macaque monkeys on a wooden staircase in a forest. One larger monkey is sitting on the railing, grooming its face. Two younger monkeys are above it, and another hangs upside down from the railing, trying to climb up. The stairs are made of concrete and wood, and the surrounding environment includes trees and ferns. The monkeys are light gray in color, and their fur appears well-maintained. The scene seems natural and undisturbed.
