SU is a comedy. It's like Miss Congeniality in a way, her dad has a lot of debt so she takes a job to go undercover to investigate a case where someone is targeting a girl... I think to kidnap her? I can't remember what the original posts were exactly when this filming news dropped. Miley had to learn street fighting for it and there's some scenes with her and guns.

She gives details there. I think it's more like she's a second generation agent from what she says in the link. I got the debt stuff wrong.
