Cat Alley (1986)

A corporate president is in the middle of a session with a call girl when he has a heart attack and drops dead. At the reading of his will, his relatives and business associates are astonished to discover that he has named a beautiful but inexperienced--in a business sense--blonde to fill his position. Intrigue abounds when members of the Board of Directors set out to ensure that she doesn't get what was coming to her, but she as other ideas.
