[1][2] The film is (loosely) based upon an Indonesian legend that the Casablanca Tunnel in Jakarta is haunted by a woman who went there in the 1970s to attempt an abortion, was unsuccessful, and died as a result.

An angry Refa lures her the Casablanca Tunnel to force an abortion, and in an attempt to flee, Astari is captured and buried alive with her unborn child.

Astari returns as a vengeful ghost known as Pontianak to seek revenge on Refa and his friends.

The reviewer panned the film as a horror, noting its sub-par sound quality, poor choices of effects, bad cinematography, bad acting, poor editing, and extreme overuse of "scary" effects, writing "they didn't have enough money to do great special effects, so instead they crammed countless of cheap effects in every scene", "bad editing can also be blamed for the ridiculous amount of loud scare noises that have been crammed into every single frame of the movie", "the incompetent director and his frantic camerawork".
