Entertainment Weekly called ‘Masters of Sex’ one of the “steamiest” shows of the season. And sure enough, it’s about to get real hot in the world of Dr. Masters and Virginia Johnson.

The trailer shows that season 2 is going to get a lot uglier - emotions, money and sex all getting tangled up in a mess. Virginia seems to get threatened right and left by Vivian Scully, a horde of doctors wanting some action and by Dr. Masters himself.

It also looks like Bill and Libby Masters’ marriage, despite the arrival of the baby, is continuing on its downward spiral. You can’t love or hate Bill Masters, quite masterfully played by Michael Sheen.

But their rocky marriage makes us wonder if that wonderful tango-dancing handyman will return this season! That’s the most fun Libby Masters had in all of twelve episodes of season 1. Let’s hope that she gets some action this season.

Lizzy Caplan has been handling the role of enduring Virginia Johnson in ‘Masters of Sex’ very well - so well that she recently scored an Emmy nomination! Watch season 2 episode 1 to see if she ace the character again.
