Investigator Ruisa infiltrates an aphrodisiac trafficking ring and secures evidence, but her identity is exposed. Bound by all four limbs, she is covered in drugged oil until her sensitivity collapses. The gang subjects her to drug-facilitated rape, forced deepthroat, toy torture, heavy squirting and hard-thrusting threesomes with repeated creampies, reducing her to their sex slave. Though she insists she will never surrender, relentless group assaults shatter her pride and conquer her with unbearable pleasure.
