On social media, whispers abound about “Cressida” — a mysterious mega‑influencer with an enormous following, said to have the power to solve anyone’s problems. Behind the account are four unknown members, each bringing their own unique skills. Operating through covert “private” accounts, they take on requests and tackle troubles from the shadows.

But their interventions don’t always lead to happy endings. Some cases end in ruthless punishment, leaving the target socially ruined.

A journalist pursuing “Cressida” suspects that the account name is connected to the so-called “Cressida Incident,” a shocking murder case involving an elementary school student that shook the public 11 years ago. What is “Cressida’s” true purpose and identity? The mystery gradually begins to unfold.
