They are 3rd-semester students who are filling their holidays by climbing a mountain located in the interior of their city. Keenan, who has conquered the climb on this mountain, invites his friends, Laras, Hasan, Tissa, Rengga, Alya, and Riki, to try to feel the sensation on the mountain, which is famous for its extreme climbing and test your courage. During the climb, they met Rico, a climber friend that Hasan and Keenan know. Rico, who has a sixth sense, sees and feels many things that he did not expect. Starting from the sound of a tiger's roar, meeting the attitude of a good guard, and other oddities. The climb that they expected would be fun and full of interesting things all changed because of one prohibition that they had violated; many illogical and mysterious events occurred: Tissa was missing, Rengga was injured, and other tense things happened on this mountain. The existence of two illogical worlds, other dimensions of life that are very different. They passed through and felt everything that became the myth of this mountain, so this mountain was finally called the Forbidden Mountain. Did they manage to get out of this mountain safely or did they end up in another life on Mount Srinjani?
That day, the lectures were not too busy.
After the semester break had started and the admission of new students had closed.
Laras, Rengga, Riki, Keenan, Alya, Tisa and Hasan were in the campus canteen while discussing the plans they would do during the long 3-month holiday.
Coincidentally they were native students of this city which was nicknamed the flower city.
Because it was identical with the beautiful flower garden panorama as if blooming in every corner of the city.
Their place of study was in the city center so most students were came from outside the city and even abroad.
There's only a few local residents that could enter this campus, because the exam tests were notoriously difficult and the fees were quite expensive.
They are 3rd semester students majoring in literature.
Laras, Rengga, Riki and Hasan majored in English Literature, Alya majored in French Literature while Tisa and Keenan majored in Japanese Literature.
While other students return to their hometowns, there are also those student who go on vacation with other friends including those who plan to spend their holidays camping and climbing mountains.
The mountains is quite far away and it was required approximately 4 hours of travel from campus to reach that mountain.
This idea came about when Keenan managed to climb there during last year's vacation.
Then he invited other friends to be able to conquer the mountain which is known for its difficult climbing track.
Many often fail and choose to go down in the middle of the climb, besides the steep and slippery terrain.
There are many rumors that this mountain is scary and holds many mysteries.
There are even several climbers who have disappeared and have not been found until now.
But many climbers are not discouraged from climbing this mountain again because of its unique natural beauty and challenges that test their courage.
Although the mystical story of this mountain is still hard to believe, its story has always been a story passed down from generation to generation since long ago.
Keenan is one of the students who is very obsessed with mountain climbing.
He has been doing this interest and hobby since he was in junior high school.
Starting from mountains with easy climbing tracks, just by going up and down in a day, to the highest mountain, namely Puncak Wijaya.
Keenan has conquered it, his hobby is still carried over until now until he entered the Mapala organization (nature lovers students).
Which consists of students who like to do activities related to mountains, forests and other natural beauty.
They also gathered in the campus canteen for the last time before it closed simultaneously during the lectures.
Except for street stalls outside the campus area who could still sell even when the campus was closed.
Laras ordered Seafood Fried Rice with her favorite extra chili sauce, Tissa only ordered Mr Edi's Milk Coffee, Hasan and Rengga ordered Special Fried Noodles, while the others ordered Batagor (Fried Tofu Meatballs).
Except for Alya who was on a diet program.
"So we want to go on vacation to Mount Srinjani that you told me about, Keenan?" Alya asked.
"It has to be, that's why I invited you all to gather here now to discuss our plan, I can't wait to breathe in the fresh air of the mountains hehehe" Keenan said while laughing.
"But I've never had any experience climbing, is it safe? But don't worry, I exercise diligently, so I definitely won't make you rest every 10 minutes hahaha" Laras said while eating the food that had arrived on the table.
"Eh but you need a health test to be able to climb this mountain because the terrain is chaotic and very steep.
There are many large rocks so you have to be physically and mentally strong to climb this mountain, and make sure that women who are menstruating cannot join first, especially those on the first day of menstruation.
Besides the physical danger of you not being strong, the caretaker there has advised female climbers who are menstruating not to climb.
Because you will enter a forest where there will definitely be things that will provoke them to do unwanted things to you" said Keenan to the six of them.
Laras who still did not understand what Keenan said about "Doing unwanted things to women who are menstruating".
"What will they do if we are menstruating?" Laras asked curiously to Keenan.
"I don't know either ras, I only know that the caretaker did not explain in detail about this prohibition, what is clear is that we are not allowed to speak impolitely, do bad things and must protect the environment there."
Keenan answered while thinking about something.
"It is said that there was once a team that did the climb, from one of them there was a woman who was menstruating on the first day, her name was Rina.
When they were sleeping in a tent in the middle of the night, Rina asked to wait to be taken to the bathroom because she felt uncomfortable because her menstruation was heavy and she was uncomfortable sleeping, after one of her friends, Putri, took her to the bathroom, and for half an hour.
Rina did not come out and when she knocked on the outside door, Rina did not answer, finally Putri broke down the door by force and how surprising she was not to see Rina there then she fell unconscious
When she woke up from her fainting, her other friends asked about Rina's whereabouts, "Putri, where is Rina? Why did you faint?"
Putri could only lower her head and cry and then said "missing, Rina is missing." While continuing to cry and Rina has never been found until now
Even all the families have searched with local residents, assisted by the police and military and the joint team,
Rina has never been found until now and the family has accepted Rina's disappearance, that's why this story is always something that must be obeyed by women who will climb Mount Srinjani.
I don't know if this story is true or just to scare you.
But once I was shown a photo of Rina, she was wearing a pink jacket and black pants, and it was said that Rina had entered another dimension or the supernatural world.
I once heard a story from one of those who arrived there, Rina had become a resident of the Forbidden Forest of Mount Srinjani, she couldn't go home or didn't want to go home.
I don't know which one is true, so the point is, if there are any of you three who haven't menstruated, I suggest you don't force them to come for your own good and all of ours," said Keenan explaining to them.
