Pacific Blue (1996) : 4x3

Russ Granger discovers that his best friend's little sister, Molly, is an underage porn star. After she resists being saved, Jamie goes undercover, hoping to nail the producer. Monica is offered ten thousand dollars to pose for Playpen Magazine, but only if she recruits the other three women from Pacific Blue. Thinking she has them all, Monica goes ahead and poses very provocatively before learning that the others have declined. Cory informs Doug of her impending pregnancy, but gets a less than enthusiastic response from the father of her child.
