I Just Clocked In, Why Did My Bullying Coworkers Die?

Clara Henson is about to start her shift when her old supervisor Irene James calls in a panic, begging her not to clock in, warning that the moment Clara does, Irene will die. Clara dismisses it as madness and clocks in anyway. Moments later, word spreads that Irene has been killed by an explosion, her head blown apart by a damaged chip. The police suspect a high-tech crime, and Clara insists it has nothing to do with her.

But Irene's final words haunt her, and her former coworker Reginald Delgado confronts her, asking why she killed Irene. Dustin Armstrong, the man who once gave false testimony against her, tells the police she is the killer. Then Dustin dies too, apparently splitting his own head open with a knife. As the bodies of those who wronged her pile up, Clara is left staring at the time clock, terrified of what clocking in might do next.
