Molly's sixth sense is warning her - danger and death lie ahead! A woman private eye in a man's world, Molly Murphy is having a hard time succeeding in running her detective agency in New York. That's why she agrees to go undercover for the NYPD to expose a pair of spiritualist sisters as con artists… even though the offer of work has come from police captain Daniel Sullivan. Sullivan had once won Molly's heart - until she discovered he has a socialite fiancée and an upcoming society wedding. Still, needs must, and so Molly finds herself posing as an Irish cousin at the uptown mansion of Senator Barney Flynn. Flynn's invalid wife hopes the psychic sisters can contact her dead son, kidnapped and lost in a sensational crime, and after a spooky séance, Molly isn't so sure the sisters are fake… but she's certain the police bungled the kidnapping case. But very soon her questions are leading her to danger… and it doesn't take a psychic to tell Molly that if she continues she may very well end up dead!
