This is a very moving story of a desperate father looking for justice for his son's  unjust death.  The scenes are well-pieced together and  the pity and compassion that one feels for the father can be overwhelming, as each scene unfolds and the identity of the murdered is revealed.  The actor playing the role of the father is also commendable and heartfelt. What makes the story more heartbreaking was the fact that  it is based on true events. The father himself admits that  he blames himself for leaving his son alone in the car and this should give a very vital message for all with regard to their children.  Engaging and very emotional!  This is a must-watch film!
