While on assignment in the jungles of Nepal, photojournalist Ted Harrison (Michael Pare) and his girlfriend are savagely attacked by a hideous beast which tears the woman to shreds and leaves Ted badly mauled.
He later returns to the States to live near his sister Janet (Mariel Hemingway), nephew Brett (Mason Gamble) and their German shepherd Thor, hoping the presence of family will dispel the horrific memories... until the inevitable effects of a werewolf curse begin to surface.
As his humanity begins slipping away, only the family dog begins to suspect something is wrong -- but poor Thor ends up being the chief suspect in a string of recent mutilation murders.
Writer/director Eric Red's script (based on the novel Thor by Wayne Smith) plays with the standard werewolf conventions -- territory already barren after being strip-mined by a plethora of Howling sequels -- but tends to retreat into cliché too often to kick it more than a notch or two above the average direct-to-video fodder.
Cinematographer Jan Kiesser's widescreen compositions lend a threatening edge to the woodland locations but are sadly lost to cable and home-video formatting.
