The Betsy (1978)

Loren, a domineering family patriarch, enlists racecar driver Angelo to design a cutting-edge vehicle, much to his grandson's disapproval. As tensions rise, Angelo becomes entangled with two women connected to Loren: his great-granddaughter and his grandson's mistress. This romantic entanglement complicates the already strained family dynamics, leading to a turbulent clash of ambition and desire that threatens to unravel their relationships. The pursuit of speed and innovation becomes a backdrop for betrayal, loyalty, and the consequences of playing with powerful emotions.
