The Good Son is a Filipino mystery family drama that follows the lives of four sons in the aftermath of their father's sudden death. Victor Buenavidez (Albert Martinez) is the perfect example of being a good father in the eyes of his sons, Enzo (Jerome Ponce) and Calvin (Nash Aguas), or so they knew because behind his good fatherly image lies a dark secret: his other family. Obet (McCoy de Leon) and Joseph (Joshua Garcia) grew up distantly with their father but when things are starting to get better for their family, a tragic accident happens: Victor suddenly dies. The two families clash with each other to clear their names for the latter's demise. How will Victor's four sons face the challenges presented by his sudden death?
