Shallow Grave

Three friends, Alex, David and Juliet share a 4-bed Edinburgh flat. They interview prospective tenants for the extra room. During the interviews the three friends act as they're the coolest people on the planet, and mock the applicants unmercilessly.

After several such interviews, along comes the mysterious Hugo, who manages to counter their sarcastic wit with his own colourful repartee. So they pick Hugo, who moves in.

But Hugo never ever leaves his room. A few day later the three flatmates decide to investigate. They find two things. Hugo's dead body, and a bag full of cash. Disposing of the body and keeping the money seems like the best solution.
