Widowed suburbanite Nancy Botwin (Mary-Louise Parker) starts growing and selling marijuana to make enough money to support her family after her husband's unexpected death leaves her in big debt. Nancy has associates in her pot-growing business, which include Andy, who is her brother-in-law, and pot-smoking City Councilman Doug Wilson.
