A search and rescue department specializes in finding loved ones lost during a war, natural disaster or relocation. The paranoid and skeptical Hong Yu-Fung, the optimistic and energetic Sze Yik-Him, the eloquent Crystal Sin, and computer expert Yeung Chi-Kei are led by a calm and rational team leader Lo Man-Kit to start their experience of searching and rescuing people. Not only do they find happiness in their work, but they also go through a whole new experience of how they see themselves.
