Nine-Tenths of the Law is a 1918 American silent drama film directed by B. Reeves Eason.

As described in a film magazine,[1] Jules Leneau (Lewis) and his wife Jane (Maye), living in a cabin in the Northwoods, are inconsolable after the death of their infant son.

Through the wicked scheme of Red Adair (Eason) and his partner, trappers who live below the Leneaus, a child from the city is kidnapped and brought to the woods.

The child wanders away and falls into a bear trap set by Jules, who discovers him there.

She is about to cast herself from a cliff when the story is brought to a happy and unexpected ending.
