On the series, according to Showtime, "Pot-selling single mom turned danger junkie Nancy Botwin has been dodging disaster since day one, but she's always had a special talent for manipulating her friends, her family, and even the law to her advantage. And the more desperate things become, the more she's ready and willing to take desperate measures, no matter who she'll have to take with her."

"Weeds" airs at 10 PM ET on Showtime. Visit Sho.com/Weeds.
