A dissatisfied woman encounters a mysterious stranger who may be her long-lost son in this peculiar, darkly comic drama. Theresa Russell plays the deeply disappointed Linda Henry, who feels stifled by a strained marriage to Dr. Henry Henry (Christopher Lloyd), who pays more attention to his model railroads than to his wife. Desperate for diversion, she is captivated when Martin (Gary Oldman) arrives, claiming to be the child she gave up for adoption after a teenage pregnancy. She immediately bonds with this stranger, but numerous signs indicate that he may not be what he seems. Strange behavior follows from everyone involved, with some of the film's most bizarre sequences concerning Dr. Henry's toy train fetish. The complex, often ambiguous script is by noted British writer Dennis Potter, who also wrote Pennies from Heaven and The Singing Detective, and Nicolas Roeg provided his predictably stylized, enigmatic direction. Despite several interesting moments, Track 29 is far from either Potter's or Roeg's best work, and most critics found it a bizarre, ineffective muddle.
