The Lesson is a 2023 British psychological thriller film written by Alex MacKeith, directed by Alice Troughton and starring Richard E. Grant, Julie Delpy and Daryl McCormack.

In the way that the movie is structured, it is similar to a play: there are only five key characters and almost the entire story takes place in one location.

The story is centered around the interaction between five main characters: an Oxford graduate, Liam Somers -an aspiring writer- who is employed as a tutor by a wealthy family living in a large house in the countryside; their teenage son, Bertie Sinclair, who is to be tutored by Liam; and, finally, the son’s parents, who are a famous British writer, J.M. Sinclair and his French wife Helene, who is an artist. The family employs a near-silent and enigmatic butler, Ellis, who is the fifth character: A person who sees everything but says nothing.
