When a child is born with rare diseases, it is usually the father that abandons the family. But not the six dads in this film-- Wu, Yung, Cheng, Li, Pan and Ouyang. Coming from different backgrounds, they do their best to care for their children while making a living to support the whole family. These dads certainly need an outlet for the pressure on their mind. They turn to music and form a rock band called “Sleepy Dads,” implying they have long been sleep-deprived for attending to their kids. With an average age of 52, they aim to hit the stage of the highly competitive Sea Music Festival. For this over-aged amateur band, it is as difficult as Apollo missions to the moon. Nonetheless, these fathers show no fear because they already lead their daily life on the edge. With incurable rare diseases, their children’s premature demise is inevitable and unpredictable. Such realization drives these fathers to live life to the fullest with their children while they can. There is nothing these fathers cannot conquer because their children’s happiness is their greatest mission of all.
