2008. Four patients are dead. The prime suspect, Dr. Tharn, vanishes without a trace. Only his ten-year-old sister, Tara, knows the truth—he was framed and murdered.

2025. Now a doctor, Tara returns to the hospital where her brother once worked—a place where shadows roam the corridors and the sky above is forever starless. During a night shift, she accidentally dials her on-call phone’s own number.

Someone answers. It’s Tharn—alive, in 2008, holding the same battered phone.

Through a fragile, time-bending link, Tara races to rewrite the past and save her brother. But in her present, the bodies are piling up again.

The killer is back.

And Tara can’t wait to meet them.
