One decade ago, Xu Lai was buried in the earthquake debris, who was timely saved by a fireman Jin Shi Chuan and his sniffer dog Zhui Feng. To soothe the injured girl, Jin Shi Chuan nodded yes to a commitment. One decade passes and Xu Lai has returned to China after finishing her overseas education and becomes a journalist and an internationally recognised dog trainer. They meet each other on a rescue site but Jin Shi Chuan fails to recognise her. Even worse, he mistakes her for a corrupt journalist. In spite of their misunderstandings, Xu Lai publishes a media report to praise the rescue team. When establishing the sniffer dog squad, Xu Lai, in the capacity of a professional dog trainer, becomes the working partner of Jin Shi Chuan, while conquering the others with her overwhelming proficiency. She even gives her rescue dog Ping An to Jin Shi Chuan to help him get out of the depression caused by the death of his rescue dog, Zhui Feng. As journalist and fireman, Xu and Jin often encounter each other in the forefront of dangers and these life-endangering emergencies will help them build a special passion towards one another.
