David Carradine and Kate Jackson spend most of their time peering over dashboards and revving up outboard motors in this extended chase film about moonshiners engaged in a frantic racing contest. Carradine is Harley Thomas, a Florida moonshiner who challenges Ralph Junior (Roger C. Carmel), the father of his girlfriend Nancy Sue Hunnicutt (Kate Jackson), to a competition to determine who can produce the most moonshine. Ralph Junior takes up the challenge and the two adversaries struggle to get the brew from their home stills to thirsty patrons without the cops or the mob trying to confiscate the firewater.
