This intriguing ensemble drama completes Lifetime’s evening of all-new, original programming.

Sandwiched between “Side Order of Life” and “Army Wives,” “State of Mind” tells the story of a woman in turmoil. (Is there any other kind of Lifetime drama or movie?)

Emmy nominee Lili Taylor (“Six Feet Under”) stars as Dr. Ann Bellowes, a therapist who has just discovered that her husband is cheating on her with their couples counselor.

This betrayal unhinges Ann to a degree, as she begins to hallucinate and has little tolerance for the whininess of her clients. She kicks her husband (who’s also a therapist) out of New Haven Psychiatric Associates, a rambling Victorian house-turned-office-building, finding young lawyer Barry White (Devon Gummersall) to fill his office.

So the premise of the series comes down to who helps the therapist when she needs counseling.

Ann finds support from some other members of the practice. These include Dr. Cordelia Banks (Theresa Randle), a psychologist specializing in families and adolescents; Dr. James LeCroix (Derek Riddell), an eccentric child psychologist; and office manager Fred Smedresman (Kevin Chamberlin).

Less supportive is Dr. Taj Kalid (Mido Hamada), a psychopharmacologist who is having his own affair, with Banks.

Slow in developing, the premiere of “State of Mind” pays attention mainly to Ann, setting up her story and her relationships to the rest of the practice. Taylor is clearly the star here, and the supporting cast gets fleshed out very little.

Still, Taylor makes Ann a likable character, and viewers will care about how things turn out for her. “State of Mind,” created by practicing psychoanalyst Amy Bloom, shows what goes on inside the heads of those trying to straighten out the minds of others.
