Katey Sagal Katey Sagal

Last season, Katey Sagal's motorcycle matriarch, Gemma Teller Morrow, was desperately trying to keep her horrific assault under wraps. But this time around on Sons of Anarchy, she's determined to uncover truths — namely the whereabouts of her kidnapped grandson, Abel — while trying to beat a bogus murder rap.

"This is a great family drama, and that's the part I love so much about it," says Sagal. "The season is all about that child and the search for him. And Gemma is struggling with being away from her family, which she hates."

For Sagal, though, she's never that far from family while on set; husband Kurt Sutter is the brains behind Sons, which was just picked up for a fourth season. "I really have a lot of respect for my husband and what he does. It's nice to be in that world with him," she says of their working relationship. "And he's a good boss!"

A boss who bravely casts his wife in such uncomfortable situations as last year's brutal rape and this season's torture and murder of Gemma's father's duplicitous nurse. "Nothing feels gratuitous to me on this show," Sagal stresses. "It's all rooted in the story Kurt's telling." Tonight that story takes some of the very pissed-off Sons to Belfast in pursuit of Abel. Sounds like the Irish won't be feeling so lucky.

Sons of Anarchy airs Tuesdays at 10/9c on FX.
