Inside is a 2023 psychological thriller film written by Ben Hopkins and directed by Vasilis Katsoupis in his feature directorial debut.

A broken thermostat renders the penthouse too hot and then too cold, and Nemo struggles with a lack of food and water, save for timed sprinklers in an indoor garden.

As weeks pass, Nemo goes hungry and suffers injuries as a result of his escape attempts, which focus on constructing an enormous scaffold from furniture to reach a skylight.

In maddening frustration, she is right outside the front door on more than one occasion, but she does not hear him banging and yelling for her to open it, because she is wearing earphones while running the vacuum.

Desperate, Nemo eats fish from the art collector's aquarium and dog food, eventually suffering from tooth decay and intermittent hallucinations.

He leaves the art collector a note written on the walls, reiterating the story from his childhood and apologising for breaking into and destroying his home, but stating that it may have been necessary as "there is no creation without destruction".
