Sheridan Smith is set to return to screens in a new drama called The Teacher, as Channel 5 has given viewers a first look at the four-part psychological thriller.
Sheridan, 40, who became a TV mainstay after roles in Gavin & Stacey and most recently Four Lives, will play senior school teacher Jenna Garvey in the new series.
Outside the classroom, Jenna is emotionally troubled and seeks to numb her pain with alcohol and promiscuity.
