Deadly Game: Undercover Boss Season 2

Alaia, the CEO of the Haynes Group, went undercover at her own Serenby Psychiatric Center to investigate a series of mysterious patient deaths. She uncovered that the facility forcibly admitted healthy people, abused and drugged them to claim government subsidies, and encountered victims whose husbands had stolen their assets, stepfathers had sold them off, or children had abandoned them. With the help of a patient named Lily, Alaia escaped and joined forces with her brother to strike back, eventually exposing her uncle Jacob as the mastermind.

He had been running the black-market hospital for profit and was also the one who had killed Alaia's parents. In the end, Alaia set a trap and brought all the villains to justice.
