Rule 101

A wealthy professor consumed by sex addiction. A group of students drawn into a forbidden ethical abyss. When a dangerous game of temptation and taboo takes an unexpected turn — a student mysteriously disappears, and everyone believes their secrets will be buried forever. But the arrival of a new face becomes the first domino to fall. The carefully constructed lies, hidden desires, and painful truths of the past begin to unravel, exposing a world of deception and obsession one layer at a time.
