In San Francisco, artist Frank Johnson, Ross Elliott, witnesses a gunshot murder as a gangster tries to squeeze money from a key trial witness. When the killer spots Frank, he fires again, and the scene escalates into a tense chase. By the time Inspector Martin Ferris Robert Keith arrives, he learns that Frank, the sole witness who could identify the killer in a lineup, must be kept in protective custody. Yet Frank, haunted by the near-death moment, notices strange bullet-hole marks on the chest area of his shadow on a wall and, overwhelmed, panics and secretly escapes from the police.
Ferris follows up on every lead and turns to Eleanor Johnson, Frank’s wife, who reveals a strained marriage and a pattern of Frank fleeing from danger rather than facing it head‑on. Eleanor, who has kept much of Frank’s life private, becomes a central figure in the search, and Ferris must balance professional duty with a personal stake in the couple’s fragile bond.
Into the investigation steps Danny Legget, a determined reporter, who insinuates himself into Eleanor’s life and publicly lends a hand in tracking Frank down. Danny’s presence adds a layer of romantic tension, as he makes overt advances toward Eleanor, while she slowly reconsiders her feelings for Frank the longer he remains missing. The police assign undercover officers to shadow Eleanor, hoping to trail Frank’s movements through the lens of the people around her.
At a Chinese nightclub that Frank frequents, Eleanor receives a note left by Frank through a wary waiter. In the note, Frank explains he will send another letter to his workplace to reveal his location, a clue that spurs Eleanor to push harder for answers. Danny discovers that Suzie, a Chinese dancer, once had a sketch of him drawn by Frank, and he steals the drawing in a bid to uncover more about the man he’s pursuing. Soon after, Suzie falls from a window to her death, and the nightclub staff are left to grapple with the possibility that she did not take her own life.
Eleanor uncovers another clue as she studies Frank’s painting at a different bar, a vivid reminder of his life and perhaps his plans. At his workplace—the department store—she finds the letter that seems to point toward a location described as “the place where he first lost her.” The message steers them toward the seaside, to a stretch of beach near an old amusement park, where Frank is quietly finishing a large sand sculpture.
As the search converges on the coast, Eleanor makes a bold move, taking a perilous roller coaster ride to throw off pursuing officers. In a tense confrontation, Danny is revealed as the villain and aims his gun at Frank. Eleanor races to the scene, and upon hearing a gunshot, she discovers Danny’s body floating in the water. The ordeal ends with a tearful reunion between Eleanor and Frank, who have weathered the danger and the deception together.
