You can't help but fall in love with Tianhuo Island. In fact, it almost makes people forget that it is in the "Ring of Fire," the world-famous belt of volcanoes on the Pacific coast. Li Xiaomeng, a young geologist, brought the team to China to make the first volcano monitoring system, the Suzaku, which is still in use today. When Li Xiaomeng's father found out about the crater, he tried to get her to leave. Li Wentao, a volcano expert who has been retired for a long time, went there right away. As Zheng Nan swam in the beautiful underwater cave, he planned to ask his girlfriend Jiahui for the same thing he wanted to do. The volcano erupted, and the fate of these people became intertwined with that of the people who lived nearby. Because they want to be able to see the sun of tomorrow, they need to make peace with the past and work together to find a way out for themselves and for everyone else who is in a bad situation. These are Chinese heroes who love and are brave, who choose and give up, who save themselves and others, and who do it all for the sake of others.
