Ten teachers from the same city and at different school levels, from kindergarten to high school, with their own purposes in mind, came to the remote Mahatma Town Experimental School to teach. However, when they were waiting for the general manager in the security room, what greeted them was not a welcome ceremony, but a bloody massacre without warning: the general manager killed a teacher in front of everyone. Before the panic spread, more terrifying rules followed, and what greeted them was a cruel "entry examination." The questions on the test paper are weird and bizarre, and the price for failing to pass is death. But the entrance exam is just the beginning, and the teacher-student game has officially begun.
