One quiet day at the hospital, Emma, an outstanding physical therapist, was busy working with a patient. Little did she know that her life was about to change when two twins entered the treatment room. The first was Lucas, who seemed confident and friendly, while the second, Ethan, had a cold and mysterious look.

As Emma prepared to treat Lucas, Ethan tried to talk to her:

Ethan: "My little sister has a similar injury, how can I help her?"

Emma (in a warm tone): "You can bring her to the hospital, and we will provide her with the necessary treatment."

Ethan smiled coldly and left the room, while Lucas remained seated:

Lucas: "I apologize to my brother, he has some problems."

Emma: "It's okay, he seems worried about his family."

In the following days, Emma began to notice strange events around the hospital: medicines disappearing, and the staff talking about suspicious people. One night, Emma overhears a conversation between the twins.

Ethan: "You always try to be the hero, but you're not going to stop me this time."

Lucas: "If Emma finds out who you are, it will ruin all of our lives." Emma quickly backs away before they notice her, realizing she's in the middle of a conflict between two siblings, one a serial killer and the other a gangster trying to control the chaos
