A brilliant but troubled Lawyer must let go of what is holding him back, save his son, and keep his family together.

A few specifics would help.

‘Must let go of what’s holding him back’: This is vague and tells us nothing. Specifically what is holding him back? What is the obstacle?

‘save his son’: From what? Drugs? kidnappers? Aliens? Since we don’t know what his son needs saving from, we have no clue to what the story is about.

‘and keep his family together’ Since saving his son seems serious, this last bit is a bit of a let down and sounds more like a b story line, I would drop it from the logline.

Hope this helps, good luck with this!
