A father reminisces about his childhood when he and his younger brother moved to a new town with their mother, her new husband and their dog, Shane. When the younger brother is subjected to physical abuse at the hands of their brutal stepfather, Mike decides to convert their toy trolley, the "Radio Flyer", into a plane to fly him to safety.
For the most part, no, but it kind of depends on how you interpret the ending (and from what I read, it seems like the screenwriter himself intended it to be "yes")
'The King' beats the younger boy on a regular basis, and at one point violently attacks him (not shown to the audience) to the point he is sent to the hospital.
