Supposedly inspired by events experienced by director John Murlowski, Black Cadillac centers on a trio of friends who are left stranded after their car malfunctions on a winding mountain roadway. Although they are fortunate enough to happen upon a deputy, they are constantly menaced by the headlights of the title vehicle. Soon the environs and the friends frayed emotions make their struggle as difficult as the troublesome car does. ~ Perry Seibert, All Movie Guide
