Clash of Egos stars Ulrich Thomsen as Tonny, an aggressive husband and father so rage-addled that he got sent to jail for KO'ing a man in public.

On one of their prized afternoons together, Tonny and the kids hearken off to see the new Harry Potter movie, but run headfirst into the discouraging news that the film is sold out.

With only one other option available to them at the cinema, the three must endure a thoroughly miserable afternoon at an über-pretentious experimental Danish film called "The Murderer," directed by the snotty passive aggressive artiste director Claus Volter (Nikolaj Lie Kaas).

Frustrated, Tonny smashes a display case in the cinema lobby (and barely manages to escape re-incarceration for it), this leads him to lose his custodial session with his children's.

Volter finds the paradox in this and gives money to Tom as a debt he is paying for watching his previous film.
