“Friday Night Plan” is a genial but utterly generic “get-to-the-big-party” teen comedy, a slow-footed Indian version of a universal formula that was never limited to just Hollywood, which has taken many a swipe at it over the decades (“Can’t Hardly Wait,””Booksmart,” “House Party”).

“Plan” is set among private school kids in Mumbai, in particular two mismatched siblings, played by Babil Khan (son of famed Indian actor Irfan Khan) and screen newcomer Amrith Jayan.

Sid, short for Sidhartha (Khan) is a studious senior at the International School of Mumbai, fretting over where to go to college, worried about grades and condemned to sit the bench on the school soccer team. He is tentative about life, and timid around classmates, a bit of a wallflower.

Sixteen year-old Adi (Jayan) is his irritating, overreaching little brother, forever “embarassing” Sid, pretty much since birth, a fact we see verified in flashbacks. Adi thinks he’s figured out how to live and thrive in school, by hanging out with Sid, his teammates and the “cool” kids.

Only Sid isn’t “cool.” Until that is, he scores the only goal that beats archrival Global School of Mumbai. A flash of notoriety, amplified by Adi’s hype, and the next thing Sid knows, he’s invited to the weekly “Friday Night Plan,” a cool kids cut-loose party. Adi will tag along, despite Sid’s best efforts. And Adi will nag Sid into asking “the prettiest girl in school” (Medha Rana) to the prom.

It wouldn’t be a teen party movie without single (widowed) mom (Juhi Chawla) being “out of town” on business. She’s told Sid to keep an eye on his brother, and stay away from her Skoda Superb sedan.

Also part of the formula, Adi’s cool super-smart and cute classmate Nitsy (Aadhya Anand) is hot-girl Natasha’s little sister Nitsy. She will be Adi’s conscience, as we know the smarmy kiss-up is about to get himself and Sid into a night of trouble.

The few laughs come from one Goth classmate’s reaction to Sid’s new “stardom” — “You’re metal!” (in Hindi, or dubbed into accented English) and the idea that the junior member of the family has to instruct his older brother in beer pong, or whatever it’s called by the cool kids of Mumbai.

Director and co-writer Vatsal Neelakantan (“Inside Edge”) dawdles through the predictable waypoints of this day-and-a-night-and-morning-after tale of partying, pranking and growing up. He wastes screen time showing us how irritated a local cop is to be caught in the soccer teams’ prank battle, shifting attention away from the kids, who at least get to turn a karaoke moment into a production number.

This genre story, almost always told with a “Ferris Bueller” flush of affluence, has a universality that kids from many cultures can connect with, and a warm familiarity that its many prior incarnations turn into expectations among adults watching it.

It’s a shame that the tale, like its hero, is so tentative, timid and slow in getting us where we know he and the film are taking us.
