Watch the new trailer for Channel 4’s new three-part drama anthology (3 x 30) On The Edge, which will air on 14th and 15th August. The dramas will showcase the work of three rising star writers and directors as part of the 4Stories initiative, the channel’s commitment to finding diverse debut drama talent.

Each drama was penned by a debut female writer and directed by directors from diverse backgrounds, who will get a national broadcast credit for the very first time.

The three bold, distinct but thematically linked films shine a light on key perspectives in criminal justice - the story of a criminal, a witness and a victim - and serve up a raw slice of real life in contemporary Britain.

The cast across the anthology includes BAFTA winner Chanel Cresswell (This is England, Trollied, The Aliens, My Name is Lenny, Murdered for Being Different, The Split), BAFTA winner Wunmi Mosaku (The End of the F***ing World, Damilola, Our Loved Boy, Kiri, Guerrilla, Luther), Alexandra Roach (No Offence, Utopia), Ria Zimitrowicz (Three Girls, Mr Selfridge), Craig Parkinson (Line of Duty, Indian Summers, Misfits) and Nadine Marshall (Save Me, National Treasure, Second Coming). Carryl Thomas (Family Affairs, Le Grand), Cyril Nri (The Bill, Cucumber, Jellyfish) and Richard Harrington (Hinterland, Requiem, Poldark, Bleak House, Larkrise to Candleford) complete the cast.
