In a modern military camp, a group of recruits with different personalities formed the "Funny Group", and they were assigned to what is known as the most difficult special training company. Under the high-pressure and "flexible" leadership of instructor Wang Yuntian, the recruits experienced arduous physical training, skills assessment, actual combat exercises and sudden crises. Every serious test, funny mistake and teamwork allowed them to gradually hone and grow, and eventually became the backbone of the Iron Army of the Republic. The story is interspersed with humorous dialogues and imaginative military anecdotes, showing "the happiest military camp" with a narrative rhythm of laughter and tears.
