Fans of Nickelodeon’s How to Rock may have felt a sting when the show didn’t receive another season, but the story isn’t over for its cast. Halston Sage, who played Grace on How to Rock, has been cast in an NBC pilot. The project is described as an action thriller drama about a Secret Service agent who faces an international crisis on his first day on the job while protecting the president’s son. Amber, one of the kidnapped students in the premise, becomes the focal point of the opening sequence. The casting signals a serious shift from lighthearted comedy to high-stakes suspense on network television, and it has fans buzzing about Sage’s return to prime time in a markedly different role.
