MID- OR LATE-SEASON entries tend to be the weakest. Or the weirdest. Last week, NBC introduced “Abby’s,” a saloon-centered comedy with all of the bite of a watered-down beer.

The CW closes out its season with “In the Dark” (9 p.m., TV-14), a noir mystery update with a twist or two.

Meet Murphy (Perry Mattfeld). She’s sassy and surly to her co-workers. She drinks to excess, to the point of blacking out. She sleeps around and stumbles through her days in a perpetual hangover.

Did I mention she was blind?

If you thought the notion of a promiscuous, foul-mouthed sightless leading lady was audacious enough, just wait. While walking unsteadily through the city streets, she happens upon the dead body of a friend — a drug dealer. She reports the crime to the police, only to become a suspect herself.

So, she does the only sensible thing. At least on television. She resolves to solve the crime, with the help of her guide dog, Pretzel.

You have to hand it to “In the Dark” for updating pop cultural attitudes. More than 50 years ago, Audrey Hepburn played the ultimate victim as a beautiful blind woman beset by drug-dealing thugs in “Wait Until Dark.” Murphy isn’t waiting for anybody’s help!

Her demons and addictions also challenge popular notions of using a blind character as inspiration (Helen Keller) or ironic poignancy (the blind hermit who welcomes Frankenstein).

The notion of a blind, alcoholic, promiscuous sleuth may seem preposterous, but the makers of “In the Dark” know that television isn’t about presenting the realistic, but selling us aspirations. Murphy’s a girl who dreams big. We’ve just got to believe!

• The eight-part unscripted series “The American Farm” (10 p.m., History, TV-PG) follows several family farms at work. Not available for review.

• “Ghost Bait” (10 p.m., Travel, TV-PG) may sound like an overlooked Abbott & Costello comedy, but it’s really ... therapy?

Producers find people with an intense fear of the paranormal and isolate them in a spot well known for spectral activities. Sounds reasonable!

Apparently, their fear helps draw the ectoplasm out of hiding, enabling the subjects to face and conquer their fears. Gosh, it’s a win-win situation.

• Speaking of the undead, “Wife Swap” (9 p.m., Paramount, TV-PG) has been exhumed.
