At his core though, he still seeks adventure, excitement and mayhem. Dena (Dakota Fanning) was born into a privileged lifestyle, but has become disgusted on the consumer society. Denouncing her family and life as she knows it, she moves across the country and starts embracing radical politics. Josh (Jesse Eisenberg), who comes from a middle-class family, has a strong belief system and will do anything to protect the Earth from destruction. With Josh as their leader, these three environmental extremists plot together to make a statement against the culture that represents everything they hate.
