[1] After an encounter with some terrorists and barely making out of the scene alive, Carson and Alfred, two brothers raised by their widowed mother Tong Shuk-fun, join the ATF together, an agency under the Security Bureau (Hong Kong).

With both brothers earning the respect and trust of their superior, ACP Steve Shum, Shuk-fun thought that it was finally time for her to retire in peace.

Unable to reinstate himself back in the team, he convinces his girlfriend Jessica, an intelligence analyst for ATF, to secretly obtain information from the force's database to help with his investigation.

The situation worsens as it is believed that the secret organisation in Hong Kong plans to spread a virus and earn money from it.
