Necessary Parties (1988)

Sinopsis

Fifteen-year-old Chris Mills isn't too happy with his divorcing parents. In fact, he doesn't want them to split at all, so he hires car repair shop owner -- and former attorney -- Archie Corelli to run interference for him and put a stop to the proceedings. It's a match made in heaven because Chris and Archie both have a deep desire to see the right thing done.
