Seven years after his father died, the old cell phone he left behind suddenly rang.
The call time shows: 23:47 tomorrow.
The woman on the phone said she was trapped in an elevator that didn't exist. There were obviously only two people in the elevator, but there was a third person standing in the mirror.
Zhou Xu thought it was just a prank until the next day, when he saw the woman who was supposed to die.
From then on, every midnight, the old mobile phone would receive a distress call from the future deceased.
On the ninth call, Zhou Xu's own voice came out:
"Whatever happens, don't answer the tenth phone call."
