This depiction of Pakistan is patriarchal and misogynistic. The almost-70 patriach of the Rana clan rules, while the son of the neighboring widow tries to control his mother. Regardless of education or qualifications, women are supposed to be housewives and bearer of (preferably male) children.
Younger son Haider is in an unconventional arranged marriage. Wife Mumtaz works at a beauty salon, while he stays home and is uncle-parent to his nieces. Being belittled and harassed by his father for not working, he accepts a job suggested by a friend as a backup dancer - to Biba, a trans woman - while telling his family that the job is a theater manager. As someone who has never left his home city of Lahore, he falls in love with this more-worldly woman, and his late-night "work" has his wife suspicious.
By western standards, the production values are erratic, and I may have missed some minor plot points due to that. The acting is believable, and the depiction of life is good (I liked the scene in the "women's car" on mass transit.) The film is daring in the subject matter of trans folk and non-traditional sexuality. I saw this at the Toronto International Film Festival, where in the Q+A the director admitted difficulty in casting Haider, when some actors turned down the role after learning of the story. The title, incidentally, refers not just to the amusement park that plays a minor role, but also to people trying to find their place of happiness.
