In the fall of 1990, five high school students from Spring City No. 7 Middle School became a disciple. Titan is the most brotherly, Monkey is the one with the best ideas, Koala is the slippery, Dayong is the cruelest, and Xiao Su is the most impulsive. They made an agreement that "no one is allowed to jump alone." Twenty years have passed, and the snow has buried everything - Titan has become the name that everyone talks about on the ground in Spring City, and it has also become the last name in the old detective's file.
