In New York's Central Park a strange event has those infected stopping dead and then killing themselves in imaginative ways. The toxin seems to be spreading into the city causing mass hysteria. Elliot Moore (Wahlberg) is a high school teacher who is fascinated by nature, and thinks he might have a theory about what is happening. First he needs to get his wife Alma (Zooey Deschanel) and friends to safety and stay ahead of the wind.

Elliot and the nursery owner figure out that they are only attacked when plants are threatened by large numbers (have you moved away from this page already?) so they split their group into three.  The wind starts to blow again and the cop takes out his gun. The Nursery owner's group don't panic but just stand and watch, and we guess they are next as you don't see any of that.

Elliot, Alma (Alma?! Of all the names to choose?), little Jess and two kids break into a model home. They soon get out as other people run to it - and as they are in a big group start to lie on the ground in front of lawnmowers and all that.

Elliot heads out towards the Allentown community. First they find a boarded up house with a disgruntled family who take out shotguns and murder the two annoying kids.

Next house along belongs to an old mad lady who takes them in. All loosely stolen from War of the Worlds. They realise she is mad and she is about to chase them out when she goes into the garden, the plants 'talk' to each other, and then she is 'infected'. She smashes her head through the window a few times. Elliot is devastated as now they are ganging up on individuals.

Alma has taken Jess to an outhouse. Elliot knows he'll die soon, so bravely steps out to spend his last moments with his wife. There's a lot of scenes of the wind. And trees moving in the wind. It's ridiculous. And then ... everything is ok.

As it turns out, with a little clue from a time title-over, the plants stopped their attack moments before Elliot stepped out.

Cut to a few months later, and Elliot is back home living life as normal in a busy community - even though surely about 99.9% of the North East of the USA would have been wiped out.  Most be full of gold-diggers living off wills, or squatters. On TV a scientist is warning about future attacks, and we're told it only affected the north east.

Next, two guys are chatting in a park in Paris when suddenly the trees start to sway again and people freeze. Again it makes no sense why it would affect EVERYBODY else except one person - maybe he's a tree hugger.

So - the first scene in Central Park - how can it affect everybody else except the woman on the bench?  You can't even argue that she might be a vegetarian - if anything the trees and plants might pick on her more for that!!  Maybe she just eats humans.
