The Witch Hunters.

Ten-year-old Jovan was born with partial cerebral palsy. Shy, self-conscious and without many friends, he often escapes in his imagination to a place where he is a crime-fighting superhero not limited by his own body. His world shifts when a new girl arrives in his class. Milica, not intimidated by much, chooses the seat next to Jovan and immediately enlists him to help her free her father from his girlfriend, whom she is convinced is a witch who has placed her father under a spell.
