One masochistic man volunteered to be a slave to Mistress Yuen, but not everyone can be a slave to Mistress Yuen. So Mistress Yuen decides to test this masochistic man to see if the man is fit to be a slave and how well he can obey her. The masochistic man desperately endures one grueling test after another because he will not be allowed to keep being a slave if he does not pass this rigorous test. Mistress Yuen then purchased a slave from the slave market to also participate in the test and pits the 2 slaves against each other to see which one can pass as her slave. And the slave test is subjected to an even harsher conditions.
