That Forsyte Woman (1957) Warner Archive Peter Graves New

In Washington D.C., the U.S. Food and Drug Administration is concerned with the increasing number of reports about the use of illegal amphetamines among long-haul truck drivers. Such pills, known as 'bennys' or 'co-pilots' provide truck drivers with uncommon energy and stave off sleep during the long trips. However, many truckers abuse the drug, becoming dependent on it to stay awake. Long-term use causes hallucinations for the user and this translates into frequent deadly truck crashes. The F.D.A. sends undercover investigator Tom Kaylor to Los Angeles to find out the source of such amphetamines in the L.A. area. Kaylor pretends to be a long-haul novice driver and is employed by local freight company Bodmer Freight Lines. He finds room and board at the house of young attractive widow Val Owens. Several other long-haul truck drivers also board at Ms. Owens' home. One of them is Kaylor's co-worker, hipster Mink Reynolds. Kaylor begins his undercover investigation to find the supplier .
