The House On Telegraph Hill is an intriguing cliffhanger set in a spooky Victorian mansion below Coit Tower in San Francisco. Victoria Kowelska (Valentina Cortese) has lived through World War II bombings and relocation camps, and has finally emigrated to America. Now she should be blissfully happy with her devoted husband (Richard Basehart) in their mansion overlooking the San Francisco Bay, but Victoria is not who she seems. Her child belongs to someone else, and her husband and housekeeper are frightening her half to death.
