After a huge fire in a certain city, firefighter Lin Qi lost his closest comrade, while music teacher Shen Nian lost his parents on the same day. The two were transferred to the reorganized fire brigade, Lin Qi became the team's devil instructor, and Shen Nian joined as a psychological counselor. Fire and water were incompatible on the training ground, but they had a perfect understanding during a rescue. Souls burned by the fire found a way to extinguish the pain in each other's eyes - to rekindle with more ardent love.
