I’m scratching my head. What is the causal link between the death of wife and the decision to turn his biker gang into a neighborhood watch team? Is he doing it out of guilt? Grief? Or is just a coincidence?

A logline is about the plot. And E.M. Forster formulated the essential nature of a plot this way: “The king died and then the queen died is a story. The king died, and then queen died of grief is a plot.” (“Aspect of the Novel”).

I see a story in the logline, but not a plot. The relationship between the wife’s death and the forming of a neighborhood watch team seems coincidental instead of causal. What’s the emotional trigger between her death and the biker’s decision?
