So we have a giant sperm in a cornfield. What? The guys have found Ma Pickett (dead) and... this thing just hanging out in the cornfield.
That doesn't go well though. Avoid sperm things in the cornfield people. So they book their asses outta there and back to the town where Wes has trouble enunciating exactly what happened, so Rob blurts out
"We found this-- this thing. This big fuckin'...monster... sperm- thing! It... it killed them!"
You don't hear that everyday. Anyway Wes decides to evacuate the town and everyone heads out. Disturbingly, even the animals are leaving. Elk and deer on the roads, dead birds... and when they get to the bridge they find Cole's parents dead, their car just sitting there like it ran into something. Actually, it did. The reverend is looking about and runs into something. An invisible wall? Cutting the bridge off from the outside world.
