Shane and Clifford have a plan to abduct the wife of a wealthy hedge fund manager. If he won’t pay them the money, they’ll snip her ears off to prove they mean business. Everything in the plan depends on everyone playing their part right to the end. It’s totally foolproof - isn’t it?

Helen and her teenage son Zach don’t really get on, until a random act of kindness brings the mysterious Bob to their front door. He seems to understand their problems and offers to help. But what effect will spending time with this kindly stranger have on their lives?

Everyone remembers the Wise Owl, of course. The bossy cartoon bird keeping children safe back in the 1970s. Those old information films had a lasting effect on all of us - especially Ronnie, who has spent his entire life trying to do the right thing. But what is right? And what is wrong?
