Uniform Stealing Board

Two men and a woman infiltrate a villain's secret caverns. The woman needs a disguise, and fortunately there's a maid right outside the villainess' chamber. They neutralize her and the woman steals her outfit.

Starts at 16:35.

A bit of an odd scene. The stone he hits the woman with is not very big and he doesn't through it particularly hard. Guess he knew just how to hit a pressure point!
