An injured criminal, Shun, is brought to a public hospital after being shot during a police chase. He is taken into the care of Dr. Tong, a neurosurgeon who is already dealing with her own professional and personal crises. While receiving medical treatment, Shun refuses surgery and continuously manipulates situations to delay his recovery, hoping for a chance to escape. Inspector Chen, the officer responsible for Shun's apprehension, watches over him closely, suspecting that the criminal's gang plans to rescue him. Tensions rise as Dr. Tong and Inspector Chen clash over how to handle the situation, each focused on their own conflicting priorities.

As the hours pass, the hospital becomes a battleground of wits and nerve, with Shun playing a dangerous game of cat and mouse with both the medical staff and law enforcement. Dr. Tong must navigate through ethical dilemmas and mounting pressure, unsure if she can trust Inspector Chen's judgment while trying to maintain her oath to do no harm. Outside forces close in, making the hospital a ticking time bomb as alliances shift, secrets boil to the surface, and everyone involved struggles to balance their sense of duty with their inner moral codes. The clock ticks down to an inevitable showdown with the unpredictable and cunning Shun at its explosive center.
