The Others want our Earth, and for that, they need to eliminate humanity. In the first wave, they take out all power and engines through a giant electromagnetic pulse. Then come the earthquakes and tsunamis, wiping out most coastal cities. The 3rd wave is a deadly form of the avian flu, spread through the 300 birds that inhabit our planet. Then, The Others inhabit the Earth, getting inside human forms to pick out the survivors one by one.
The fifth and final wave is about to come, and the US Army enlists help from the children who've survived the apocalypse to fight the Others. Outfitted in battle gear, the kids are sent out into the battlefield. Yes, it makes no sense... and neither does most of the rest of the movie. But when you are about to eliminated from the face of our only planet, who has the nerve to question?
There can be only 2 reasons to watch The 5th Wave this weekend - you have already seen Airlift and Joy, AND, you are a big fan of Chloe Grace Moretz, who is cute as hell.
