In Plain Sight ends its third season tonight and while it isn’t necessarily a cliffhanger, series star Mary McCormack says we can expect to want more.

“You always want to leave a few seeds planted,” she acknowledges. “I think our finale achieves that.”

Don’t ask for details on that ending, however, but she does tells HollywoodOutbreak.com that the director of the episode was her own husband Brothers & Sisters Executive Producer Michael Morris.

“He directed the finale last year, too,” McCormack points out. “I love it. I have to hire him to see him.”

The finale begins 10:00 p.m. ET/PT on USA Network.
