Exit Protocol

After architect Ethan dies in a supposed car accident, his younger sister Lina finds a hidden wall safe with a cryptic note warning her to never trust his words. She uncovers a secret closed psychological group run by Greg, which masks itself as a self-help circle. Its core scheme trains members to master manipulation and erase evidence, eliminating those who discover the truth—Ethan and another victim Daniel were both murdered for exposing its dark agenda. Lina infiltrates the group undercover, secretly recording conversations and collecting confidential files. She cooperates with police to arrest Greg and convict him of multiple homicides. Later, Lina launches a hotline to help people trapped in toxic secret organizations, carrying on Ethan’s unfulfilled mission to expose hidden harm.
