Doubles Cause Troubles

Nurse Liang Shan Bo and Actress Zhu Ying Tai are mismatched cousins who just inherited a rental home from their late relative. When they moved in, they discover that a room has been rented out to a man named Ben, who turns out to be a criminal gangster.
One night, when Ben returns home, bloodied and injured, he collapses into Ying Tai's arms and whispers a code in her ear before he dies. Not knowing what the code leads to, Ying tai and Shan Bo are later visited by a man claiming to be Ben's brother who wants to solve the case.
