Plot

Naina Catherine Kapur is a pessimistic, uptight Punjabi American MBA student who lives in New York City with her widowed mother Jennifer, a Punjabi Christian, disabled brother Shiv, adopted sister Jiya and paternal grandmother Lajjo, a Punjabi Sikh. Jennifer runs an unsuccessful café with her neighbour, Jaswinder "Jazz" Kapoor. Lajjo is hostile to Jennifer and Jia as she believes that Jia's adoption led her son (Jennifer's husband and Naina's father) to commit suicide.
