Young geologist Li Xiaomeng brought her team here to develop the first volcano monitoring system "Suzaku". Li Xiaomeng's father, Li Wentao, a volcano expert who has retired for many years, rushed to the crater after learning about it and tried to persuade her to leave. At the same time, exploration expert Zhengnan was diving 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 tomorrow, they must reconcile with the past and work together to find a way out for themselves and all living beings in desperate situations. This is a story about love and courage, choice and giving up, self-rescue and other-rescue Chinese heroes.
