Bill Ingram is looking forward to a Christmas visit with his adult daughter, Carol, and is waiting for her train to arrive at the station so he can take her home. The train arrives at the station a few minutes late… but Carol isn’t on it, nor is she on the other two trains coming in from London that night. Convinced something is terribly wrong, Bill goes to the police, but finds little help. Determined to find his daughter, Bill embarks on his own investigation, discovering a secret lifestyle involving a seedy nightclub and unsavory people who led Carol down a dangerous path. Bill is willing to do whatever it takes to find her, no matter what—and the cost will be higher than he ever imagined.
