A poor man learns that obtaining wealth through evil means can command a terrible price in this made-for-TV horror story. Jeff Obold (Aiden Gillen) is a struggling auto mechanic whose personal life is a good bit more rewarding than his career; he has a lovely wife, Marla (Nina Siemaszko), and a seven-year-old daughter Casey (Skye McCole Bartusiak) whom he dotes on, even though he has a hard time providing for them. One day, while looking for parts for a vintage muscle car, Jeff makes the acquaintance of Bruno Rubin (F. Murray Abraham), a mysterious but charming stranger. Jeff and Bruno learn they share an interest in classic cars, and Bruno invites Jeff and Marla to visit him at his estate. The couple soon discovers that Bruno is very wealthy, and soon Bruno shares with Jeff the source of his wealth and power -- a strange demonic creature called a "darkling." The darkling can bestow untold material fortune on anyone willing to be its companion, but Jeff finds doing the darkling's wishes has a price when his association with the demon costs him his beloved Marla -- and Casey's life may be next. The Darkling was produced for the USA cable network.
