Young geologist Li Xiaomeng brought the team here to develop the first volcanic monitoring system, the Suzaku. Li Xiaomeng's father, Li Wentao, a volcanic expert who has retired for many years, rushed to the crater after learning about it, trying to persuade her to leave. At the same time, expedition expert Zheng Nan dived in the beautiful underwater cave, preparing to give his girlfriend Jiahui a romantic proposal. The volcano erupted, and the fate of these people was entangled. In order to see the sun of tomorrow, they must reconcile with the past, and work together to find a way for themselves and for all sentient beings in a desperate situation.
