A medical student wearing a lab coat is standing on top of the school building. Unsteady and sweaty, his position allowed him to fall at any moment.

School security was seen trying to prevent him but as soon as the door to the top opened, the student fell. The students huddled below were hysterical.

A narration then sounded. A woman’s voice said that we all know humans need at least 8-10 hours to sleep, but never know how long a human can last without closing their eyes. The scene continues when a lecturer is seen explaining about sleep disorders or insomnia.

He told medical students that insomnia was a physical disorder with mental roots. Stress and anxiety can disturb the mind and prevent people from falling asleep, but this usually lasts no more than two days, except in cases of serious clinical insomnia.

Still according to him, people with extreme insomnia experience sleep deprivation for months or even years. This is triggered by something more complicated than stress, such as the impact of the trauma he experienced. He then shows an audio visual , an image of someone who is sleeping but doesn’t look restful.

The lecturer then asked: what happens if humans stay awake for months, even years? While one or two sleepless nights are enough to mess up the human mental capacity which is called emotional deviation. More than three sleepless nights will cause acute confusion and delirium disorders.

When it does, our perception of reality will be distorted. If the condition lasts longer than that, a person will experience auditory and visual hallucinations so that they cannot distinguish between what is reality and what is not.

The film continues when a young woman named Jane (Panisara Rikulsurakan) tells that the longest time she hasn’t slept was three nights. At that time he and his sister, Jane, had just moved into their grandmother’s house.

Since living there he has been worried about the safety of the house. Every night he kept checking the lock even though he knew it was locked. He couldn’t help but keep double-checking.

The girl didn’t seem to feel burdened, she could even see this disturbance from a positive side because it meant she could make the most of the 24 hours she had. One morning Jane received a letter notifying late payment on a home loan. There is written the amount of money to be paid, which is 728,155 Baht.

Jane, who is studying medicine at Sirindara University, submitted a request to stop because of financial constraints. The lecturer who at the beginning explained about insomnia, tried to persuade him. The lecturer, known as Professor Nichcha, then remembered that a pharmaceutical company from Germany had contacted the university.

They are looking for volunteers to research a new drug. The lecturer heard that the pay was quite large. He also felt that from the interviews they did about insomnia, Jane qualified. Jane then took the business card that her lecturer gave her.

The story continued when the girl received an explanation about Qratonin from a German pharmaceutical company that her lecturer recommended. It is a substance that originates from a part of the brain called the thalamus.

Qratonin can be used to treat brain dead patients and this substance is only produced when we are awake. On that basis, the pharmaceutical company from Germany started an experiment called Deep.

They describe the processes in the Deep which consists of three levels. The higher the level, the more concentrated Qratonin will be. The duration of each level may be different for each person. This experiment can only be carried out by personal Weimarers or personnel from the organizing pharmaceutical company.

Soon a middle-aged man named Hans Miller came to see Jane. He is Deep’s research director. Hans began to explain the experiment he was going to do with reference to Alexander Fleming’s success in discovering penicillin which had revolutionized the pharmaceutical business.

Hans wanted Qratonin to do the same. Jane then asked, why is Qratonin only produced when humans are awake? Hans replied by saying that if melatonin is a substance that can make us sleep while Qratonin is the opposite. Jane again asked the question, this time about how much money did she get from this research?

Deep review

Hans said that for level one, each trial participant gets 100,000 Baht. Jane readily agreed and signed a consent form, which included agreeing to have her implanted with a microchip in the occipital area. This microchip will only take Qratonin from the brain. Hans then inserted the chip into the back of Jane’s neck.

The man said as long as Jane had a microchip on her neck, Jane should wear the watch provided. The clock will measure Jane’s heart rate and the amount of Qratonin that has been obtained in percentage terms. Before leaving the room, Hans reminded Jane not to fall asleep at all.

If Jane sleeps for more than 60 seconds, the microchip may have a short circuit which could cause Jane’s heart to stop. Jane looks to be starting to panic but Hans guarantees that this experiment is safe because the clock will also warn Jane if she accidentally falls asleep. Then can Jane through this experiment?
