In Plain Sight Episode 4.10 Girl, Interrupted

Pregnant or not, Mary Shannon has never been very good at unwinding. Which is why, in an attempt to force relaxation on her, Stan and Marshall hatch a plan to get her out of town. With Oscar riding shotgun, Mary heads into the desert to deliver a message to one of Marshall's witnesses, a new age alpaca farmer who just might have some insight to offer into Mary's current situation. And with a file full of prospective adoptive parents and some tough decisions to make, Mary could certainly use a little guidance, even if she is reluctant to heed the advice of a New Mexico mystic. Or a dog.

Meanwhile, Marshall and Stan are forced to tackle the crisis of Mary's witnesses Britt and Kenna, a feuding mother-daughter duo. It's the usual teenager-rebelling-against-a-controlling parent routine, except for the minor fact that Kenna, a former teen rock star who witnessed a murder, is being hunted by some very bad guys who would very much like to see her dead. While blue-streaked hair and a spot on a local choir don't seem like the end of the world, Kenna's seemingly minor acts of teenage rebellion constitute major security breaches-and just might be leading killers right to her doorstep.
