Crazy Japanese imperialism wreak havoc on the living power of the CCP's underground party and many revolutionary comrades sacrificed vigorously. Underground party member Xia Jia He was assigned by the organization to prepare to take the radio to Dalian. He was hunted and blocked by Japanese Police Officer Junji Aoki on the way. When there was nowhere to go, Xia actually met his first love, Wang Da Hua. Taking this as an opportunity, Da Hua and current husband Tang Quan Li were involved in this series of events. Da Hua Qing broke her family and wanted to save her husband, but could not change her husband's fate. Da Hua thus hated Xia Jia He, who had harmed her and lost her happy life, so she seized the radio station and did not return it to the other party.
