Equipped with the self-confidence of a shark, Marla Grayson works as a professional and court-accredited caregiver for numerous senior citizens, whose assets she seizes in a highly dubious but legal manner. Marla and her business partner and lover Fran also use their well-oiled machinery with brutal efficiency on their latest "conquest" Jennifer Peterson - a heavily wealthy senior citizen who has no living relatives or heirs. But when it emerges that Jennifer is also carrying a similarly dubious secret and has connections to an unpredictable gangster, Marla has to shift up a gear in order to prevail in a battle among adversaries that is neither fair nor honest.
