Magnum, P.I.

Magnum tries to impress a beautiful 'fan' of Robin's by showing her the Robin Masters estate, only to learn that she is actually a top security expert hired by Robin to test the estate's security. J. "Digger" Doyle and her boss, David, are hired by the absent Robin Masters when his life is threatened if he publishes his latest manuscript. On the chance that the tapes he uses to dictate his novels are at the estate, Higgins is kidnapped by a group seemingly led by a woman named Lisa. In a surprise twist, Magnum comes to the rescue, foiling the kidnappers and the man behind the scheme.
