Locked in

At 8:17 p.m., every exit in Tower 19 suddenly locks shut. The power flickers. Phones lose signal. Then the residents begin acting strangely—not like zombies, but as if something is controlling their minds. They become faster, stronger, and violently obsessed with spreading an unknown infection. Twenty-three-year-old Kai Ren, a quiet maintenance worker, teams up with six strangers trapped inside the building. As supplies run low and trust begins to crumble, they discover the outbreak didn't start by accident. Deep beneath the apartment lies a hidden laboratory, and someone is still watching them through the security cameras. To escape, they'll have to survive not only the infected—but also the secrets of Tower 19.
