On a train platform, Clay brings the report that Peter has succumbed to jungle fever, leaving him paralyzed. Marie goes with him to the dark and spooky manor on this rainy night. Peter is jovial enough, but there’s something not right that Marie can’t quite put her finger on with her uncle’s butler and secretary. Peter shows off his trophy room, full of artifacts from his years in the jungle.
The morning finds dismal weather, but Marie doesn’t want her uncle to know about the nightmare she had the night before, with the shrunken head. Weeks pass, and Marie settles into her new home. Her work with manuscripts, and professors at the university lead to disappointments for her. Her nightmares continue, and soon she has to tell her uncle about it.
After checking the artifacts, the shrunken head is found missing. The nightmares keep getting worse, and soon uncle Peter starts thinking his niece may be losing her mind. Is Marie in some real danger? Who would want her out of the way? Secrets are revealed, but the Whistler has the last one.
