The Red Jacket (2002)

A German father's soccer-playing son is hit by a car and dies. The father donates the boy's red jacket to charity, where it ends up in war-torn Sarajevo. The boy's parents are killed, and he almost is. Some UN soldiers find him, and send him to a hospital in Germany. He escapes the hospital, is hit by a car (but unhurt). The driver reads the tag inside the jacket and "returns" the boy to the grieving father.

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