Hollywood sex symbol Rainer Devon stresses about his domineering mother producer Nina casting his next film opposites in the latest 'Locked' franchise movie, especially his colored enemy Jordan Wilder, whose success is won in the sack. Rainer expects the female co-lead to go to bitterly rivaling starlets Alexis Glenn or Dakota Nichols, but the open 'for show' audition actually yields a surprising third shortlist candidate to Rainer's taste. It's shy utter newcomer Paige Townsen, who was dragged along by pushy airhead college roommate Cassandra Perkins and needed encouragement from their smart, hunky roommate Jake Salt. Rainer is delighted when Paige, whom he flirts with, is contracted, undeterred to send gifts and invitations. The rookie's instant fame distracts the press from scandal sought by a vindictive reporter whom Nina needs to deal with whatever it takes.
