Determined to break away from her family's tempestuous history of less than legal pursuits, Danna Pavalek has made a career in the entertainment world. When her brother is murdered, she at first supposes his death must relate to his drug running activities. But as the FBI becomes involved and rumors mount that his last cargo was a fantastically valuable one, she finds herself drawn into a deadly race to find it.
