A highly mediocre movie that descends into a disjoined mess as the filmmakers apparently changed their minds three or four times about what they wanted it to be.
A team of douchebags stays at an inn in France for high-altitude cycling training when a huge wave of serial killings hits. But wait, it’s not serial killings, it’s a pandemic. But wait, it’s not a pandemic, it’s a strange mist that assumes human form and kills people by touching them and turning them funny colors. But wait, it’s aliens. One by one everybody dies, disappears, or kills each other until one couple is left. Hooking up in an out-of-place and overly long romance montage, they decide to go for a final swim outside and allow themselves to be taken by the aliens, who finally put in an appearance but decide not to kill them for reasons that are a mystery. A final newscast reveals it was not aliens, it was AI, and the reason some people were spared is a mystery, but the attack is over. Then the ground is shaking as the invasion begins again. The man of the final couple makes a “final journal entry” in a voiceover as a “warning to whoever hears this” about AI, which is strange, because, the AI already is there and took over, so who is he warning about what? The final couple is seen walking down a street in the French mountains. A glossy, digitally-animated UFO appears in the foreground of an overhead shot looking down on them.
Or you could just skip it.
