The House on Telegraph Hill 1951

Viktoria Kowalska, a Polish woman who has lost everything in the German occupation, is imprisoned in the brutal Belsen concentration camp. There she befriends Karin Dernakova, a fellow prisoner who clings to the hope of reuniting with her young son, Christopher, who was sent to live in San Francisco with a wealthy aunt. As their world tightens around them, Karin’s quiet dream becomes Viktoria’s dangerous route to a new life.

Karin dies shortly before liberation, and Viktoria seizes Karin’s papers to assume her identity. The camp is freed by the Allies, and Viktoria is interviewed by Major Marc Bennett, who arranges a path for her as a displaced person. She writes to Karin’s Aunt Sophia in San Francisco, only to learn through a lawyer’s cable that Sophia has died, leaving Viktoria with a stark, unclear fate to navigate.

Four years later, Viktoria—still living under Karin’s name—travels to New York City, where she meets with Alan Spender, the distant relative who is Sophia’s representative and guardian of Chris. Viktoria’s plan is simple on the surface: secure custody of what she believes is “her” son. But she soon discovers that Sophia’s fortune was left to Chris when he comes of age, a twist that makes it easier for her to stay in America if she becomes Mrs. Spender. With this realization, she agrees to marry Alan, and the couple heads to San Francisco, where Chris meets his “mother” for the first time and the family settles into Sophia’s grand Italianate mansion on Telegraph Hill, under the same roof as Alan’s devoted governess, Margaret.

What begins as a glittering domestic ideal quickly spirals into tension. Margaret—who has raised Chris and harbors strong feelings for Alan—resents Karin’s intrusion into their carefully balanced life. Karin is unsettled by the eerie presence of a burnt-out playhouse overlooking the hill, a place Chris says he damaged with a toy chemistry set. He and Margaret urge Karin not to tell Alan, but her curiosity grows, especially when she learns that Alan seems to know more than he admits about the incident. She also suspects foul play after the car brakes fail on a day when Chris was meant to be with her.

With Marc Bennett’s help, Karin begins to untangle the web, probing the accident for proof. She reveals her true identity, and Marc confesses he is in love with her. He also hints that his father’s firm might not have sent Sophia’s fatal cable, leaving Karin more nervous about Alan’s grip on the truth—and on Chris’s future. As she digs deeper, she discovers Sophia’s obituary tucked in Margaret’s scrapbook, confirming the cable was sent before Sophia’s death and implying Alan’s direct involvement in prior crimes.

The tension peaks as Alan’s control tightens: he attempts to poison Karin with a late-night dose of sedatives in the orange juice they share, a ritual he believes will secure his hold over the family. Karin, however, has swapped the glasses, foiling his plan and exposing his guilt. He drunkenly confesses that he murdered Sophia and that he has tried to orchestrate a fatal ending for Chris as well. With help from Marc, Karin tries to call for help, but the phone is off the hook, and the moment seems to seal Alan’s fate until he drinks from the poisoned glass and dies on the spot.

Margaret, though implicated by her inaction, is arrested for refusing to aid Alan in his crime. In the wake of the tragedy, Karin and Marc, with Chris in tow, depart to start anew, leaving behind a life built on deception to embrace a future defined by truth, new roots, and a chance at genuine family.
