This video suffers from an identity crisis: is the Neptune of the title the Roman god of the sea, or is he the apelike caveman from The Hills Have Eyes? Director Vincent de Paul can't seem to make up his mind, and Malcolm Ford, who plays the title role, sometimes lounges in his hot bath like an Olympian deity and sometimes grunts his way around the mountains like a retarded ape.
Various campers and hikers become the focus of this sexual lust, which keeps the "plot" moving. Then there's the second scene by a pool, which seems unrelated to anything that comes before or after. If anything makes the viewer pick up this tape, it will be the box cover, which proves that Ford is in fact a very attractive man.
