It stars David Thewlis, Laysla De Oliveira, Rossif Sutherland, Alexandre Bourgeois, Arsinée Khanjian and Luke Wilson.

Because of Veronica's refusal to let him help her, Jim finds himself unable to emotionally support his daughter, and begins to take out his frustrations via his work as a food inspector.

Veronica emphasizes Jim's commitment to his work as a food inspector and his ability to care for the family's pet rabbit, Benjamin, who died at the improbable age of 16.

Jim would also regularly visit Veronica in prison where she was previously serving a sentence for having had sexual relations with an underage teenage boy named Clive when she was a high school music teacher.

Later that night at a motel, Veronica, Clive, and another male student spend time alone in a room and purposely make a lot of noise to trick Mike into thinking that they are partying and having sex.

Veronica begins to have a flashback to the suicide of her teenage boyfriend, Walter, causing her to panic and storm out of the room in plain sight of Mike who then confronts her.

A series of flashbacks reveal that Veronica began regularly taking music lessons at the private residence of a woman named Alicia when she was eight years old.

Alicia is a single mother who also teaches music to her son, Walter, who is of a similar age to Veronica, and the two children would go on to regularly perform together at recitals.

Towards the end of Roseangela's life, Jim and Alicia began developing a romantic relationship which was facilitated in large part by Veronica's music lessons.

Veronica claims that she remembers seeing her father holding hands with Alicia while she was performing at a musical recital despite the fact that her mother was still alive and in attendance, a charge which Jim denies and tries to disprove while emphasizing that he could never love anyone as much as Roseangela.

Veronica also claims to remember seeing Alicia follow her father upstairs to presumably have sex during her music lessons which had merely become a pretext for their blossoming relationship.

Jim inspects an Armenian restaurant called Wild Orchid and discovers two major violations pertaining to their processing of rabbit meat in the kitchen.

The restaurant owners convince Jim that the rabbit meat is for a private event and is not for sale during a regular dinner service, but he is skeptical and intends to come back to verify their claim.

During a tense conversation, Clive truthfully explains what happened during the school trip which led to Veronica's imprisonment, and he tells Jim that the bus driver was the one who sent the inappropriate text.

Later that night, Jim returns to Wild Orchid and discovers that there is in fact a special event taking place at the restaurant, and he is unexpectedly the family's guest of honour that evening.

He expresses his desire to kill the bus driver who was responsible, causing him to be reported to the police by the restaurant owners after they send him home in a taxi.

[2] In November 2018, David Thewlis, Luke Wilson, Laysla De Oliveira, Rossif Sutherland and Alexandre Bourgeois joined the cast of the film.

The site's critical consensus reads, "David Thewlis' performance aside, Guest of Honour serves as a frustratingly limited return to form for writer-director Atom Egoyan.
