King of the Jungle(2000)

He was just a kid in a man's body until his mother's killer made him a man with a gun.

Seymore is a young man with the mind of a child. He loves three things in life: basketball, sneaking out for cigarettes, and his mother. But all life's simple pleasures are brutally torn from him when he witnesses his mother gunned down by a neighborhood punk. Now Seymore must overcome the child within as he rises up to fight for some kind of justice. It's a fight that will take him out into the streets where there are few friends and many enemies -- and one of them is a killer who wants him silenced.
