Thirty-year-old Lyra Cole’s younger sister Blair dies mysteriously three months after enrolling in the prestigious Pearl Dance Academy, ruled by the corrupt founder Harrison Nash. Refusing the police’s overdose verdict, Lyra disguises herself as a new student to infiltrate the cruel elite school for revenge. She endures Harrison’s humiliation and tyranny, allies with his aggrieved secretary Margot to collect criminal evidence. Lyra cleverly eliminates the vicious helper Chloe and lets Harrison’s righteous son Alexander witness his father’s dark crimes. Finally, Harrison’s dirty money-for-power transactions and atrocities are exposed, and he is arrested and ruined. Alexander decides to assist Lyra in fighting for justice for Blair.
