At a first glance he looks like a homeless person, dressed in weird stuff including a see-through raincoat with lots of random dirty electronics attached. To keep everybody in line he announces he has a bomb and the "suicide vest" looks pretty convincing to the diners.
He claims this isn't the first time he's been there, the endeavour has failed numerous times, but maybe this time will be "the win".

Gore Verbinski mines tons of sci-fi media for this slightly unhinged time travel/loop story. There's a dash of 12 Monkeys, and a smattering of Black Mirror episodes all bodged together with cable ties. You can spot all the little bits that have been stuck together but it manages to fall on the "great artists steal" side of the line.
Having recruited the hapless team we get flashbacks showing how some of them have already interacted with the coming apocalypse in the last few days in a way that hints it might actually already be too late. The section with Juno Temple's character is one of the darkest things I've seen stuck on screen for quite some time.
The actual mission is to travel a few block across town and insert some 'guardrails' in the AI via a gizmo the unnamed man has with him. Simple in principle but even prior to its full ascension the AI is pulling at the strings of the world and dangerous or weird stuff stands in their way. Having been seen before, some of it is navigated a la Edge of Tomorrow with foreknowledge of the certain death that dogs their steps.
Beyond a certain point it's all new, weird, territory.
This one of those things makes me wonder how it got developed. It's not a franchise. It's not safe but also not anything like a typical "indie" project which are often safe in a different way. Maybe somebody was just looking for another "Everything, Everywhere, All at once" and this is what we got. It doesn't have the inventiveness of the latter and it looks cheap in places but it's an unusual little chaotic goblin of a movie 8/10.
