A gay stuntman whose wish of becoming a woman gets accidentally fulfilled when he has to run away from a deadly gang after witnessing a murder. After the operation, she could have lived a low-key life if her father had not gotten so sick, and the only opportunity presents to her is the chance to enter a beauty contest. Thus our hero's journey begins when she fights her way to the top prize, while diverting the gangster's assassin, the disgruntled ex girlfriend, bitchy fellow contestants and nosy fashion bloggers.

Set in an old apartment complex where a family lives in a single cramped room, Nhà Ba Tôi Một Phòng portrays the “out-of-sync” relationship between a conservative father and his dream-filled Gen Z daughter. As generational differences collide within the confined space, their bond is tested and gradually mended. The film offers an intimate slice of contemporary Vietnamese family life, where love often begins with understanding.
