Showtime ordered “Guerrilla,” a limited series from creator John Ridley, starring Idris Elba. The six-episode drama will be broadcast in the U.S. on Showtime and in the U.K. on Sky Atlantic. ‘Guerrilla” is a love story set in one of the most explosive political times in U.K. history, the miniseries tells the story of a 1970s London couple who liberates a political prisoner and forms a radical underground cell. The group targets the Black Power Desk, a true-life counter-intelligence unit within Special Branch dedicated to crushing all forms of black activism. Though set against a backdrop of social upheaval and activism, the story focuses on the relationship between the two characters at its center.
