Paige Townsen is a normal college girl working on her business degree who enjoys acting on the side. When the next big movie franchise goes into production and opens its doors looking for the next “It girl” to play the lead role, Paige’s roommates Cassie and Jake convince her to go to the open casting call. Never in her wildest dreams does she think she will even make it to the callbacks, but after an electric audition with Hollywood heartthrob Rainer Devon, her chance of a lifetime happens. She gets the part and her life is about to change forever. Meanwhile, intrigue is flowing through Hollywood as every actor wants a part in the new “Locked” film.
On the eve of the big "Locked" cast announcement party, Paige is more nervous about telling her parents the truth about snagging her dream role than the actual event. With her parents set on her education taking priority, she tries to find a way to convince them - and herself - that she can do both. Meanwhile, the gossip is still swirling about Rainer and Jordan's fight over Tangey, and Nina is determined to shut it down so it won't hurt the film.
Having promised her parents that she would be able to balance school and the film's schedule, Paige quickly learns that it is easier said than done. While trying to work on a crucial school paper, she keeps getting sidetracked with wardrobe fittings, photo shoots and screen tests. Leaning on Jake and Cassie for help, Paige quickly learns she may be in over her head. Meanwhile, Nina must make cuts to the movie budget, and Jake meets with an agent about his script.
Paige becomes aware of the realities and pressure that come with starring in a 200 million dollar film, as her first day on set is riddled with difficulties. Her on-set relationship with Rainer causes further complications with Jake, and she's forced to make a professional decision. Cassie's schooling is in jeopardy after struggling with tuition payments, and with no options available, she's forced to make a tough decision. Meanwhile, Tangey and her mother argue over the future direction of her career, which threatens her mother's status as her manager.
Jordan and Tangey renew their relationship in secret; Rainer surprises everyone when he throws Paige a surprise birthday party, but things don't turn out as expected when Jake arrives late.
Nina and Rainer take a last-minute trip to China to rescue Locked from a new setback, which derails Rainer's weekend plans with Paige. But when Alan and Rainer bond over their mutual tastes, Nina feels uncomfortable. Cassie's financial problems continue, so she feels forced to take more shifts as a topless maid. Meanwhile, Jordan deals with issues involving his mother.
Thinking it would help Cassie's financial problems, Paige offers her a job as her assistant. When Cassie declines, issues in their friendship are revealed. Plus, Jake starts to learn the realities of what it means to sell a script in Hollywood, and Alexis embraces her role as Producer on the project. Meanwhile, Jordan's problems continue to mount as he learns Brandy needs more money, and Barrett Hopper reveals to him that he knows the truth about his and Brandy's past.
Paige and Cassie's fight is impacting Paige's performance, and when Jake is too busy to help, Rainer offers his own advice. Later, Jake's career takes an unexpected turn. Meanwhile, when Alan and Rainer spend some time together, Nina grows concerned. On top of her worries, she's facing a possible lawsuit, and she agrees to help Jordan with his mother's issues. Rainer surprises Nina with a helpful solution, but her happiness is short-lived when her worst fears about Alan and Rainer are confirmed.
Paige deals with Jake's impending move to Austin, and a revelation about Cassie fractures their friendship. Meanwhile, Rainer starts searching for his real father, but he's thrown into a tailspin after he puts the pieces together. Later, Jordan tries to mend his relationship with Tangey, who feels betrayed by his secret. But when he shares information about his past, she considers forgiving him.
