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. Then there's the business of trying to keep the whole thing secret from people like her neighbor Celia.

Peter stops playing nice; Celia and Doug's affair turns serious; Nancy and Conrad make a devil's bargain.

Nancy's big day is marred by Silas' disappearance, Shane's inflammatory graduation speech, and Celia's madness.

Nancy goes in search of Silas and her hijacked pot; Celia has Silas arrested for stealing her '`Drug Free Zone`' signs; Nancy visits Silas in jail and discovers that the pot is still in his car.

Nancy must strike new deals with Heylia and U-Turn; Celia must leave; Andy faces consequences for his good deed.
