Self Defense (1932)

"The FIRST LAW of NATURE!"

Katy Devoux runs a gambling-drinking joint in British Columbia. She is a fair-playing business woman, but is ashamed of the source of her income, so she has had her daughter Nona raised in the states. Jeff Bowman, an unprincipled scoundrel and business rival, arranges for her daughter to come to town in hope of bringing shame to the mother. He overplays his hand and is killed by Tim Reed, a faithful retainer of Katy's and in love with Nona. The plea is self defense.
