It takes a while to get one’s bearings with “The Modern Way,” a drama set among Britain’s working class “Mods,” famed for the scooters, sharp dress and passion for The Who and Rod Stewart’s Faces.

The Mods’ traditional rivals were the Rockers, greasers in blue jeans, white T-shirts and leather biker jackets.

But in Jake Henderson and Giuseppe Monticciolo’s “The Modern Way,” the Mods’ rivals are Skinheads, who favor acid-washed jeans (?!). Space Invaders was all the rage and the band Madness was on the way up.

And lo and behold, there’s a bloke with a Ford Cortina equipped with a cassette deck.

So this genre drama about gangs, drugs, Vespas and Lambrettas and age-old blood feuds is set during a brief “Mod Revival” that peaked with the release of The Who’s album and the film “Quadrephenia” in the late 70s.

It’s a tale with “back in the day” Mods and Rockers still existing in a state of unease, but now older, working and running businesses. Some of those pre-Thatcher-era businesses — in the case of Rockers turned Skinheads — are illegal.

The kids coming up are the source of much of the drug trade — pill-popping and other “gear” — and the violence.

Frankie (Ashley Hodgson) hangs with his mates Leon (Leon Dean) and Millie (Alice Handoll). He’s sweet on Millie, and she might actually return the affection if he ever “makes his move.”

But Frankie has other concerns. He makes his living dealing street drugs on behalf of aged Skinhead Harvey Grey. And on the night we meet them all, somebody sees Frankie pick up drugs from some goons, stash them on his scooter, and go back to drinking in the pub.

His Lambretta is stolen and torched and the drugs disappear. He’s in deep trouble with scary Harvey (Nick Cornwall) and his scarier lieutenant, Jerry (Jordan Louis).

The Skinhead hanger-on Danni (Grace Long) is the one who set the conflict to come in motion by fingering Frankie’s Lambretta as the one to steal. She’s living with her ever-blitzed mother and mum’s junky-beau, so she’s got her own problems.

Jack Parr of “Peaky Blinders” shaved his head to play Mason, Danni’s controlling tormentor, who stops sniffing glue long enough to lead his mates in stealing those drugs and torching that Lambretta.

And co-screenwriter Jake Henderson, in his first starring role, plays Terry, the “adult” Mod in the room, friend to Danni’s family, gainfully-employed but still tough enough to hold his own if the wrong sort get in his face.

The disorienting nature of the early scenes, with their ’60s music and actors poorly made-up to cover the holes from era-inappropriate nose piercings (and those damned acid-washed jeans) distracted me into ticking off anachronisms early on.

Once it becomes clear (ish) what the real era is, the generic story and plot complications and underwhelming set pieces reminded me of “Northern Soul,” another intriguing glimpse into a corner of Brit pop culture history botched in the execution.

There’s no tension and rising suspense over Frankie’s ticking-clock debt. The much-discussed Mod scooter convoy down to Bristol for a weekend of partying is set up and talked-up, briefly-shown, and that’s the end of that.

Violence finally comes and the instigator of all that goes wrong is brushed-over, forgotten and left unpunished, just like in real life.

While some effort is made by the geezers to “explain” the Mod/Rocker rivalry that goes back decades, it’s still a head-scratching dead end.

The picture winds up being such an uninteresting shrug that one is reminded of what Ringo said in “A Hard Day’s Night,” when asked if he was a “Mod” or a “Rocker.”

“Um, no. I’m a Mocker.”
