From IMDB:

One-off drama based on the critically acclaimed memoirs of British journalist Sathnam Sanghera. A touching, humorous and emotional rites-of-passage story.

From  Acorn TV:

Based on a critically acclaimed memoir, this BBC drama is the touching and humorous story of Sathnam (Sacha Dhawan, Iron Fist), a second-generation Indian raised in Britain, who struggles to reconcile his traditional upbringing with his multicultural modern life. “Soul-searching and impeccably acted” (The Telegraph), it also stars Joanna Vanderham (The Paradise) and Deepti Naval (Lion).

From Acorn TV you can stream this 87 minute complete film.

Without giving anything away, the underlying motivation for the story is that Sathnam wants to marry a white girl outside his Punjabi culture and is afraid to tell his mother. Years ago he left his family to work in the white world of London journalism. When he returns to his family (in another part of London) he makes many discoveries about his family of which he was blithely unaware starting with the fact that his father is schizophrenic.

Call this film a “rare find” or small “gem of a film”. In any case,
