Going into the DVD store I found this thriller movie called Harlequin (1980). It stars David Hemmings, Carmen Duncan.
The plot goes like this:
When a prominent politician is somewhat mysteriously, but apparently accidently drowned while scuba diving, the press focus on the young Senator Nick Rast who seems strongly favoured to succeed the dead man and by doing so raise himself up another rung on the ladder of political power.
Rast, whose marriage to Sandra was a political convenience, nevertheless shares his spouse's concern over their young son Alex who is stricken with leukemia. While doctors hold out no hope for the child, Alex is visited by a strange, flamboyantly mystical faith healer, Gregory Wolfe whose administrations in the presence of his parents effect a miraculous recovery in the boy.
Wolfe's appearance at Rast's closely guarded mansion is made all the more astonishing when the Senator realizes he has managed to evade all the elaborate security systems in gaining entry.
Gradually Wolfe becomes part of the family circle and as Alex continues to gain strength and abnormal powers from his instruction and philosophy, Sandra falls more and more under his spell. However Rast's political backers, personified by the ruthless Doc Wheelan view Wolfe in a very different. They begin to plot against him, worried by Sandra's increasing dotage and dependence and her growing refusal to present a happily married front to the media. Even Nick recognizes that Sandra's initial gratitude to Wolfe has turned to love.
