In a dystopian future with absence of resources, people can freely to inn The Pit, a vertical underground jail where after an interview to check the possible admission, the volunteer passes a determined time in exchange to get more social position. Hoping to get an approved title, Goreng wakes up in the level 18 to discover The Pit’s structure: only one cell of 6 meters height (so-so 20 feet) per level with a rectangular hole in the middle in all them, used by The Pit’s administration to descend a too rectangular floating platform with the food for all prisoners, downing from level 0 (the restaurant where food is cooked) to the bottom, staying 2 minutes per level. With veteran Trimagasi as cell’s partner, Goreng learns eventually The Pit’s main rules: 1st, each inmate arrives The Pit with a personal object from the exterior; 2nd, the inmates can’t keep food off the platform under penalty to die by extreme heat or cold; and 3rd, one time per month all inmates are asleep with gas in order to exchange them of levels. But when a month later they both wake up in the level 171, Goreng learns for his horror that all the inmates divide in three types: those in the upper levels who eat with more time to think, those in the lower levels whose don’t eat after platform arrives empty becoming in demented and starved killers, and finally those who jump to the void by the hole, crashing against lower levels (and being cannibalized by the savage inmates). Saved to be killed by Trimagasi in the last minute by Miharu, a silent and violent young girl who time and time again descends in the platform looking for her missing child forced to be in The Pit, Goreng little by little loses his mind in a place with no morality nor humanity, passing from level 23 to 252 with Imoguiri as partner (Goreng’s interviewer and an ingenuous about the reality of The Pit) to finally arrive in level 6 with Baharat as new partner, who tries with a rope scaling to level 0. But Goreng tells Baharat a better plan to leave The Pit.
