Richard Davalos plays Rick Bowman, a drag racing street punk who comes to the attention of car enthusiast Grant Willard. Willard bails him out of jail and offers him sponsorship as a race car driver. Bowman eventually accepts and becomes entranced by the tricky “figure eight” track Willard introduces him to. The king of the track is cocky and talented hot dogger Hawk Sidney (Hill regular Sid Haig in one of his most memorable and entertaining roles). Bowman and Sidney clash and Bowman sets his sights on knocking the latter of his perch while stealing his girl Jolene. This is just the beginning for the ruthless Bowman who will let nobody stand in his way and will attempt to destroy any man, and seduce any woman who crosses his path. Pretty soon he has his eyes on Ellen McLeod the wife of champion racer Ed McLeod who he befriends. Will he betray his friends and colleagues on the eve of The Big Race, or will he finally discover he has a conscience?

In the waning days of WWI, a U.S. “Mystery Ship,” sets sail for the coast of Spain towing a submarine. Their mission is to find and sink a U-boat that has been especially effective in attacking Allied shipping. Posing as a harmless schooner, the mystery ship is in fact fitted with a formidable gun capable of sinking a U-boat. Stopping in the Canary Islands to refuel, the crew interacts with locals involved with Germans, and with Germans themselves, including the sister of the U-Boat commander, who is lurking offshore waiting for the coming battle.
