Boy Missing (2016)

A young lad goes missing, presumed kidnapped by some rumbuggers. After a somewhat frantic search, he turns up unharmed but emotionally silenced by his ordeal.
His single-parent mum decides to take revenge on the kidnappers. However, being a very high profile lawyer, she reaches out to some dodgy types to do the dirty work. As you have probably guessed, the plan goes a bit bollock-shaped and she digs herself into something of a hole.

Yeah, pretty good.
