Helen's Dead

When Addie decides to surprise her cousin Helen at a dinner party by confronting her for sleeping with her boyfriend, she's the one in for a surprise. When she gets to the party, she discovers her cousin is dead and realizes everyone in attendance is a suspect. Now, instead of revenge, Addie has to exact justice for her cousin, complicated by the fact that another boyfriend of Helen, violent ex-convict Henry, wants some justice of his own.
