So...this crazily optimistic, sci-fi kid's movie was co-written by Lenny Bruce. Not sure what we can learn from that, but it seems worth noting.
A little boy obsessed with atomic age space stuff gets a special laser gun from...a ghost, and is then fostered by Justice of the Peace Amelia Brown, a woman with so much faith in humanity that it borders on the absurd. After Justice Brown has a run-in with a local political boss, he attacks the local orphanage, knowing it will hurt her, while awaiting an election that can cement his power base into the next century.
Oh, the kid's toy gun has all kinds of magical powers, too. But it's basically the deus ex talum needed…
