Mistress Kat, a slim brunette with piercing eyes, runs a kickboxing school for three incompetent male slaves. When the slaves fail miserably at their martial arts moves, Mistress Kat strips to a black teddy, which pushes her sharp nipples directly into the slaves' faces. With the help of the gymnasium equipment, Mistress Kat whips and degrades her slaves until the three defeated men cower in submission. Unfortunately, the single-position, fixed-camera photography dilutes a good deal of the fun.
