Channel 5 viewers hypothesised Sheridan Smith's character in The Teacher was the victim of a "set up", while watching the new drama on Tuesday evening.
Many The Teacher viewers even predicted the character of Emmerdale actor Kelvin Fletcher could be behind the accusation she slept with an underage pupil.
Sheridan, 40, has returned to screens as senior school teacher Jenna Garvey in the new four-part psychological thriller on Channel 5, which aired its second episode on Tuesday evening.
