Trying to remember an American documentary (probably mid 90s- early 2000s) about spanking. There are three families who advocate the use of corporal punishment, they are very strict and religious. The mothers teach their children at home and punish them if they don’t behave. In one scene a mother asks the son if he finished his homework, he says yes, but she finds out he is not telling the truth and decides to punish him, goes to his room with a switch and we hear him scream.
