Sorry, Lorna, I overlooked this. But yes, really silly. Mostly the problem is that it couldn't make up its mind what kind of movie it wanted to be. It has a dark opening; a factory burns down and a man dies in the fire. Cary Grant is arrested and tried for arson and murder (but since he's Cary Grant, we know he didn't do it). During the trial, he attacks his guard and escapes.
Then for some strange reason we get a whole string of screwball comedy scenes. That's followed by scenes of pseudophilosophical discussions of law, freedom, and human rights. Next is the mystery of who really set the factory on fire, finally solved. Then the movie turns political, and Ronald Colman (a law professor, not practicing law and certainly not a judge) is appointed to the Supreme Court. It's all wrapped up in Washington, D.C., with a little romance thrown in at the end for extra flavoring.
