White Line Fever

On the open road, Jan-Michael Vincent plays Carrol Jo Hummer, a stubborn independent trucker, and Kay Lenz is Jerri Kane Hummer, his pregnant wife. They become entangled with crooks who run a freight scheme and the powerful boss behind it. The couple refuses to stay quiet as threats pile up, testing loyalty and the bonds of partnership. As days on the highway turn into a high-stakes chase, he must choose between protecting his family and staying true to his own code. The conflict pulls in friends and rivals alike, turning a routine haul into a tense battle over money, integrity, and survival. Vincent anchors the role with a steady, no-nonsense presence, while Lenz grounds the tension with practical warmth.

Directed by Jonathan Kaplan and released in 1975, White Line Fever comes from an original screenplay by Ken Friedman. It marks Kaplan's early foray into hard edged street cinema, balancing character grit with action, and pairing strong performances with a lean, efficient style.

Box office details are not widely documented, with no readily available grosses. The film lives on as a mid level entry in Kaplan's filmography rather than a marquee hit, appealing to genre fans.

Reception is modest, with a 6.0 out of 10 rating from about 50 votes. The film centers on a working class couple pressed by crime, and its tight pacing reflects 1970s genre sensibilities. Themes of loyalty under pressure, the lure of quick money, and the price of independence on the road anchor the drama, giving it a grounded texture amidst action.

While it may not be hailed as a cinematic landmark, White Line Fever sits alongside 1970s road crime dramas that lean into blue collar grit. It features Jan-Michael Vincent and Kay Lenz in a tense, real world romance set amid car culture and crime.
