While being instructed to investigate some transnational crimes, OCTB officers Hui Chun-sum (Ruco Chan) and Shum Wai-lik (Ben Wong) find out that Ngai Chi-lok (Cheung Wing Hong), the culprit behind the Tiger Cull case, sent some secret message to the dark web before he was apprehended, and transferred a substantial amount in cryptocurrency. And soon some mysterious person plots to launch a terrorist attack. Although Chun-sum and Wai-lik solve the case with the help of the talented Prof Tong Kwun-fung (Alex Fong), they are shocked to realize there are some more evil conspiracies hidden behind Chi-lok. While crisis escalates in the workplace, there are also challenging love issues. Chun-sum hopes to be reunited with his ex-girlfriend Ma Wing-sze (Lam Ha Mei). However, the couple's relationship is kind of iffy as they have deal with so many problems.
