On an apparently normal night, Jill Johnson, a teenager, is hired as a babysitter to care for two small children in a remote house. From the beginning, the atmosphere is tense, and the feeling of unease quickly settles in. While the children sleep, Jill begins to receive strange and disturbing phone calls from a stranger. At first, she thinks it's just a prank, but as the calls escalate, she realizes something is not right.
The unknown caller not only knows her name but also seems to be very close to her, which sends the situation into a state of terror. In a moment of panic, Jill tries to contact the police, but bureaucracy and lack of evidence work against her, leaving her at the mercy of this stalker. As the tension mounts, the story turns into a terrifying struggle for survival, as Jill realizes that the real danger is right on the other end of the line.
With each call, time runs out, and the pressure to escape increases. What started as a simple babysitting job transforms into a horrifying nightmare where not only her life but also the children's lives are at stake. The film plays with the fear of the unknown, leading us to question who the strangers really are and how safe we are in our own homes.
