Clad in black leather and astride her powerful motorcycle, newlywed Rebecca (Marianne Faithfull) sets out alone across the European countryside on a passionate and dangerous journey to visit her lover, Daniel (Alain Delon). As the road stretches ahead, her thoughts spiral into a dreamlike montage of freedom, erotic memories, and emotional conflict-caught between a stifling marriage and the thrill of desire. Blending surreal visuals with 1960s counterculture energy, this cult classic explores liberation, love, and the thin line between ecstasy and self-destruction.
