San Francisco, a roller coaster, and Brian Keith's father as a cop. What more could you ask for? Very effective noir with Sheridan as a woman searching for her husband, who witnessed a gangland killing and is now in severe danger--in addition to having a heart condition. Might as well pile it on, folks. Only false note is that their marital difficulties are portrayed as all her fault! He's just a misunderstood artist who gives away his paintings and turns down $500 prize money (a lot in 1950) because he "isn't ready yet!" Nice cast and atmosphere. ( )
