Mary-Louise Parker is back as pot-dealing widow and single mother-of-two Nancy Botwin for a third season of this hilariously subversive series. Thanks to the unresolved murder of Peter, her DEA agent boyfriend, Nancy has yet to see the light at the end of the tunnel. And it isn't just the Feds she has to worry about--Peter's ex-wife, Valerie (Brooke Smith of THE SILENCE OF THE LAMBS), is also on the prowl. Of couse, that is just the beginning of the madness. Her teenage son wants to help out with the family business, her live-in brother Andy (Justin Kirk) ships out for Iraq, and dangerous drug dealing associate U-Turn has Nancy by the stems. Meanwhile, on the bureaucratic side of the Agrestic township, unscrupulous real estate developer Sullivan Groff (Matthew Modine) is shaking things up between council members Celia (Elizabeth Perkins) and Doug (Kevin Nealon). Mary-Kate Olsen (THE WACKNESS) also guest stars as the new girlfriend of older son Silas.
