Bathed in the shimmering summer light, the six episodes in Frisky Summer 4 are happy, playful and joyful expressions of your youthful sexuality. Tim Hamilton finally has his long-awaited romantic tryst with Danny Saradon; Gilles Marais, in his feature debut, tops new, cute blonde Robbie Martin; and lanky Pierre Delon has two scenes, one with Marcel Bouvier and the other with Adrian Kinski.
