Costumer Joey Jessop is working on a movie set in 1930s Hollywood and starring two of the world's biggest stars. The male lead is also a dedicated social activist, and the female lead, Gillian Best, is known for her lifestyle brand. After a hit-and-run near the set, Joey realizes that the car involved belongs to Gillian, and she begins to wonder if the actress has more to hide than her Botox appointments. Her suspicions deepen when Gillian's personal assistant, Rita, vows to get revenge for Gillian replacing her and is found dead shortly after. Gillian quickly labels Rita's death a suicide, and the police seem to agree–but Joey isn't so sure. With the police standing aside, it's up to Joey to dig up the truth—but Hollywood stars know how to keep their secrets close, and a woman like Gillian Best won't take kindly to someone sniffing around her affairs. Joey is certain that Gillian has something to hide—and she's determined to find out what.
