Colin Beavan is a New York City writer and self-proclaimed liberal. He has big plans for his new book. He decides on a grand experiment: to live one year with as little impact on the environment as possible. The problem is, the project requires his wife Michelle, an espresso-guzzling, Prada-worshipping business writer, and their young daughter to be fully on board. The family embarks on a year of no electricity, television, cars, toilet paper, elevators, or newspapers.
