Based on a famous MMORPG in Vietnam. Thang, a shy and impoverished university student, spends most of his time playing the popular online martial arts game Swordsman Online instead of studying. In the virtual world, he transforms into the fearless hero "Anh Hung Co Lau" and befriends a beautiful player named Bao Huong, unaware that she is the girlfriend of Minh, his arrogant class leader. When Thang's growing reputation threatens Minh's dominance in both the game and real life, their rivalry spirals into a series of outrageous confrontations.
