'Grey's Anatomy's' Shonda Rhimes sells FBI drama 'Under the Gun' to NBC

The Shondaland empire is expanding again: "Grey's Anatomy" creator Shonda Rhimes has signed a development deal with NBC for "Under the Gun," reports The Hollywood Reporter.

"Grey's" scribe and producer Peter Nowalk will write the script co-executive produce with Rhimes and Betsy Beers.

According to THR, "'Under the Gun' revolves around Erin Kain, a woman who goes to work for the FBI as she struggles to make sense of a terrible event in her past that ruined her life and tore her family apart. While her young and fragile appearance doesn't typically suggest that she's best suited to work as a field agent, her dark past helps her get inside the head of criminals who were normal one day and cracked the next."
