Mary-Louise Parker in "Weeds."

A lot can happen in three years, as is proven in the first episode of the new season of Weeds. It makes its Canadian debut Wednesday on Showcase.

As the seventh season begins, the story leaps ahead three years, as lead character Nancy Botwin (Mary-Louise Parker) has been in prison for that amount of time. At the end of the sixth season, Nancy had taken the fall for a murder committed by one of her sons.

At least Nancy was safe behind bars. But she understandably is terrified when she suddenly and unexpectedly is released.

“I’m supposed to go into witness relocation ... I have a deal!” Nancy bellows.

“They’re sending me to a f------ halfway house. Esteban (her drug-lord husband) is going to have me murdered. No protection, no answers, nothing! What am I supposed to do?”

If the first six seasons were any indication, Nancy usually figures out something.
