National tasks cannot be violated. Shen Heng went to eastern China to work as an undercover agent, but after being discovered, he was tortured for 54 days and then rescued.
One of his kidneys was cut off and his legs were damaged. He could only walk after rehabilitation.
When he didn't go to the east, he and Chen Sijin made an appointment to spend the rest of their lives together.
Shen Heng went to the east for 2 years, and Chen Sijin waited for 2 years before they met in the hospital where they were working.
They thought they could spend the rest of their lives together, but unexpectedly a criminal escaped from prison.
Intention: Is the thought of justice and evil just the emotion of this thought?
