Ward 13 tells of a pair of friends namely nat (endhita) and mina (luna maya) who was driving a car and accidentally hit someone. The man is named hera. Feeling sorry for sympathy, nat and mina agreed to bring a fainting hera to the hospital. But when they got to the hospital, all the patient rooms were full. It does not escape because many patients are being treated on the day. Because the condition of the hera continues to decline eventually the hospital was forced to open a room that had been closed. Namely room ward 13. The room itself even locked.
After the hera is treated there, the hospital that does not know that grout and mina is the perpetrators of herna ordered them both to keep the hera until later siuaman. The two of them who do not want to get into trouble because of being caught hera finally agree with it.
But one of the sisters there first cautioned the two friends about the prohibitions that should not be broken when they were in the 13th ward. That is, they should not heed the mysterious beats from outside the ward 13 and they also should not knock on the door of the ward 13 from inside. The nun also did not tell us more about why the ban was imposed.
Sure enough, when the first night they stayed in the ward 13, there was a mysterious knock from outside the ward 13. Nat curious then wanted to know the origin of the knock on the door. Mina had forbidden it because of the ban given by the nun. But nat did not care, he also welcomed the knock. And there was no one.
Nat who was disappointed then broke other rules that he knocked on the door of ward 13 from inside. And from there the horror began to come to the two companions. They begin to be visited by the noseot nuns who haunt them. Initially, the frightened mina invited grout to get out of the ward 13. But nat refused. They both have to stay until the hera woke up, so that later they will not have to deal with the police. The decision makes them both have to continue to face terrible terror coming from the ward 13. Ward 13 is a horror-themed movie.
