The Netflix hit series "House of Cards" is a rollercoaster ride for its binge-watching fans. If haven't yet finished watching the 13-episode run of Season 2, here's a spoiler alert: We're going to spend time talking about one of the best subplots in House of Cards.

This subplot has to do with a hacker, Gavin Orsay, played by Jimmy Simpson, who's been compelled to work for the FBI in order to avoid a prison sentence.

In order to get all the tech-talk right, producers brought in consultant Greg Housch. He's a hacker who's been involved with the online group Anonymous since its inception, and in 2007 he spent seven months in federal prison for his illegal online activities.

Housch says he's now a "reformed" hacker and he joins Here & Now's Meghna Chakrabarti to discuss helping out with "House of Cards," kicking back with the likes of Kevin Spacey and Sebastian Arcelus.
