F is a 2010 British horror film directed by Johannes Roberts and starring David Schofield, Eliza Bennett, Ruth Gemmell, and Emma Cleasby. The film takes place in a failing inner-city school in London where a group of teachers are attempting to educate a class of unruly and violent teenagers.
One day, after school hours, a gang of students break into the school and begin terrorizing the teachers, trapping them inside. The gang, led by a student known only as "N" (played by Fadi Elsayed), is armed and dangerous, and the teachers, including the determined and resourceful Robert Anderson (played by David Schofield), must band together in order to survive.
As the night wears on and the violence escalates, secrets are revealed and tensions run high. The teachers are forced to defend themselves against the brutal and relentless attacks of the gang, and they soon discover that their survival may depend on their ability to outsmart and outfight their teenage assailants.
F is a tense and suspenseful film that explores themes of violence, power, and the consequences of societal neglect. It is a chilling reminder of the dangers that can arise when violence is left unchecked, and a powerful commentary on the need for greater understanding and support in the education system.
