Captain Duy Kien and the NH1 Marine Police team took on the task of rescuing fishing vessels from pirates. When the mission was completed, Captain Duy Kien was on leave and an incident during the holiday helped Captain Duy Kien meet the beautiful doctor Hoai Phuong.

Captain Duy Kien's heart began to shake before Hoai Phuong. What would he do to approach her? Unfortunately on the very first date something come up…

Doctor Hoai Phuong joined the health counseling program and gained a surprise. Hoai Phuong's group was sent to Hai Phong island to participate in a charitable campaign where it was where Captain Duy Kien was working on duty.

Duy Kien's coldness transformed after beautiful memories between him and Hoai Phuong. At the same time, Sergeant Bao Huy was forced to leave Hai Phong Island. What is the cause?

In Hai Phong Island, Hoai Phuong's group of doctors simultaneously faces emergency cases and the threat of royal guards. To protect the life of the ambassador's son, Duy Kien's action has the potential to raise tension in diplomatic relations between the two countries.

Bao Huy attended the wedding of his ex-girlfriend and faced a series of unexpected situations. Hoai Phuong after hearing that Duy Kien was about to be disciplined, rushed to ask question.
