The Double McGuffin(1979)

It’s all about getting away with murder!

The Double McGuffin is a family adventure film about a group of schoolchildren who discover a briefcase stuffed with cash near their school. When they return to retrieve it, they find a dead body instead—but both vanish before they can alert authorities. The police dismiss their story as a prank, leaving the kids to investigate alone. As they dig deeper, the children uncover a sinister assassination conspiracy and realize they're the only ones who can stop it. Caught between criminals who want them silenced and adults who won't listen, the young sleuths must gather evidence and expose the plot before it's too late. The film balances suspense with humor as ordinary kids become unlikely heroes in a dangerous game.
