The Kite (1999)

Though widowed ex-cop Homer is a kindly father to his ten-year old son Rex, he is considered to be something of a bully in the poor Manila neighborhood that he lives. After mistaking a child retrieving a snarled kite for a burglar, Homer kills the boy and then hurriedly tries to cover up his error. Unbeknownst to his dad, Rex witnessed the event, too. As the two separately wrestle with their consciences, the neighbors find out and chaos soon ensues.

Unfortunately the movie The Kite is not yet available on HBO Max.
