The hiring of a new assistant triggers a power struggle between an aging TV show creator and her former protégée. Rising-star showrunner Stacey McCreedy has one goal: to leave behind her nerd-girl origins and become a power player — like Ann Dalloni, her former mentor and current producing partner. Ann, meanwhile, is feeling her age and losing her mind. But she’ll be damned if she cedes control of their hit primetime TV show to Stacey. After Ann hires Jenna, a young actress hoping to restart her stalled career, as an assistant, the relationship between Ann and Stacey deteriorates into a blood feud. Soon, Jenna must choose whom to support and whom to betray to achieve her own ends. And Stacey will find out if she possesses the killer instinct needed to stay on top.
