"... A cart horse standing on a street. A man comes and fits a gas mask on horse's head. It looks the same as the one people use but the shape is adjusted to fit horse's head. Horse is not happy about it. The man sits on the cart and rides off. The mask does not seems to affect horse's performance.
Various shots of other cart horses being fitted with gas masks. Several shots of the horse with gas mask on pulling cart through streets. Several shots of the horses with gas masks on being lead through the streets by men.
