Ace is a burglar who picked the wrong house to rob. Sneaking in a dark house can be dangerous when Wonder Woman (played by Mary Jane) is patrolling the neighborhood. He denies it at first, but when she uses her lasso on him, he has to tell the truth. And he confesses that he is down on his luck and needed to rob the house to get by. Mary Jane is sympathetic but insists he still needs discipline. So she gives him a hard, powerful spanking to correct his behavior and teach him a valuable lesson.
