And you thought the Swiss were the only ones famous for their cheese.

“Project Silence” hurls a disparate group of Korean strangers onto a fog-enshrouded bridge on the way to Seoul Airport, trapped by a mass traffic pile-up that includes a vehicle transporting deadly (CGI) attack dogs.

Our hero, Cha Jeong won, must protect his rebellious teen daughter, dodge the crashes and the possibly collapsing bridge, evade the dogs and the commandos sent to deal with them. And since he’s deputy director of state security, he’s doing all this while trying to maintain a media blackout, government spin and a coverup.

Of course, every daunting thing listed above — and I mean EVERYthing — is destined to bite him in the ass.

Director and co-writer Tae-gon Kim — “The Sunshine Boys” dramedy was his — does his best to let us in on the goof this picture is. But as striking as the foggy setting can be, as impressive as the scale of the pile-up turns out to be (rivaling “The Blues Brothers”) and as silly as one character and a couple of seriuously excessive moments struggle to be, “Project Silence” never quite finds a tone and rhythm that works.

Cha Jeong won, played by the late Lee Sun-kyun (“Parasite”), is an outspoken (by Korean standards) political insider who, whatever his government job, always has his eyes on the next election and his boss winning it. He’s a widower ready to send his bratty daughter (Kim Su-an), to study abroad, which might help him focus more on work. Not that he isn’t wholly into that already.

But a troubling hostage situation dominates the political agenda and serves as the backdrop to the off-kilter evening he and many others are about to experience. That fog, that bridge, and a lot of cars, buses and an anti-terrorist superdog transport are about to meet.

Cha Jeong won tries and fails to throw his weight around with military underlings and a mysterious “doctor” (Kim Hee-won) who stays glued to his computer and has Cha Jeong won handcuffed for being a nuisance.

Dr. “It Wasn’t My Fault” is trying to rein in — via computer chip commands — the anti-terror dogs he created, who seem to be in attack mode — coming after anybody in a uniform or otherwise in their way.

Comic relief is provided by sketchy “punk” tow-truck driver Jo Park (Ju Ji-hoon), who tries to cheat one and all, who complains and runs and yells “Cut the DOG crap!” (in Korean with subtitles), a fellow whom nobody seems all that intent on helping, but whose lapdog Jodie everybody wants to save.

And then there’s the cranky young golfer Yoo ra (Park Ju-hyu) and her hapless manager Mi ran (Park Hee-bon). At least one of them has a weapon at hand, if the other one didn’t wreck or lose those clubs.

The political intrigues take a turn in a direction we wholly suspect, the action beats run out of things to blow up and character types lean into type as all of this haphzardly comes to a head.

There’s just not a lot to make a lot of here, despite “Project Silence” being Lee Sun-kyun’s final film, despite efforts to give this CGI-bathed clunker a lighter touch, despite all the cars they crashed even as no “real” dogs were harmed in the making of this movie.
