Viewers who know Gale Storm only through her chaotic comic performances on TV's My Little Margie and Oh Susanna will be surprised by her subdued dramatic performance in Abandoned. Storm plays Paula Consodine, who comes to Los Angeles in search of her missing sister. Newspaperman Mark Sitko (Dennis O'Keefe), investigating on Paula's behalf, discovers that the sister is dead, a supposed suicide. The whole thing seems a bit fishy to Sitko, and indeed it is: the girl's death was engineered by a black-market adoption racket, headed by one DeCola (Will Kuluva). Paula bravely offers to act as bait to draw the criminals out, a formidable task given the presence of such secondary villains as Raymond Burr and Mike Mazurki.
