1982, Crane City. Snow and ice cover not only the streets, but also people's hearts.
Chen Jianjun, known as "Little Four", is one of the countless young people who have been thrown into the cracks of the city by the tide of the times. His family was poor, so he dropped out of school to make a living. He bounced between the construction site and the kitchen, experiencing cold looks and bullying. It wasn't until the winter when he was seventeen years old that he followed his third brother into the neon-dazzled "Paramount" dance hall, and the gears of fate began to turn in an unpredictable direction.
From the waiter who swallowed his anger, to being forced to show his claws to protect his dignity; from the "little brother with three scars" to the "little four" who made his name in the west of the city with his life-threatening ruthlessness. The trajectory of his struggle is a bloody road steeped in survival instinct, loyalty and cold reality.
The conflict in the ballroom was just the prelude, and the street fights were not the whole story. This is a survival guide for the young people at the bottom. Between the end of the planned economy and the tide of the market economy, between family responsibilities and personal solutions, between humble survival and violent dignity, he must find his own way of living.
Cold times, hot blood. Without protection, they become wild beasts.
This is a story about transformation - how a person is forced to awaken the ferocity in his blood in the harsh reality, growing from a lamb to a lone wolf licking his wounds alone in the cold night, but always looking towards the dawn.
Here, loyalty is the only currency and courage is the final capital. And "living" itself is the most thrilling world.
