Dylan McDermott and Maggie Q star in “Stalker”

These days, you’re probably seldom given pause when you tweet about the concert you’re at or post a shot of your meal at the restaurant you like to frequent. With everyone and his dog running rampant on social media, we’ve all made ourselves extremely accessible to our friends and family, but that giant window into our lives can't always be a good thing.

CBS’s new series is going to have the masses scrambling for the privacy settings on Facebook pages everywhere. “Stalker” is a suspense thriller about -- you guessed it -- stalkers. More specifically, it’s about the people who investigate incidents of stalking and put a stop to them before the threats get really out of control. The psychological drama premieres Wednesday, Oct. 1, on CBS.

The network’s lineup is already pretty laden with crime and suspense, so execs must figure you can't have too much of a good thing. “Stalker” will be joining prime-time heavyweights such as “Person of Interest,” “The Good Wife,” “NCIS” and “Criminal Minds” on the roster this fall, and if the pilot’s anything to go by, it’s likely to be just as compelling as its fellows.

The series is centered around the LAPD’s Threat Assessment Unit. It takes a look at different aspects of stalking and intimidation, showing fictionalized versions of things that actually happen to people in real life. In fact, CBS president Nina Tassler calls the series “the scariest drama the network has ever aired.” The detectives look into cases of voyeurism, cyber harassment and romantic fixation; determine what kind and degree of threat the victim’s under; and respond before the stalking and intimidation can turn into something worse.

Enter Lt. Beth Davis (Maggie Q, “Nikita”). A victim of stalking herself, Davis is an expert in the field, strong and focused, and doesn’t take any guff. That makes wise-mouthed Det. Jack Larsen (Dylan McDermott, “American Horror Story”) a perfect foil for Davis, his new boss.

Larsen has recently moved to Los Angeles after transferring from New York City’s homicide division. He’s got a strong personality and a certain swagger that have gotten him into trouble before, along with some dubious past behavior that will actually prove useful in his new position. There’s a certain mystery to Larsen; he’s trying to change from the man he’s been in the past, yet at the same time, the very transgressions he’s trying to leave behind are what will give him valuable insight into the minds of the creepy culprits he’s after.

Rounding off the team are detectives Ben Caldwell (Victor Rasuk, “How to Make It in America”) and Janice Lawrence (Mariana Klaveno, “True Blood”). The youngster of the group, Caldwell lacks the level of experience his teammates have, but he’s nevertheless eager to learn and play his part. Smart as a whip, Lawrence is a key member of the team, and her exceptional brain power will prove to be invaluable. We’ll get a look at how the team works together and complements one another, while also getting to know them as people dealing with their own lives and obsessions.

Maggie Q and Dylan McDermott as seen in “Stalker”

The show is a long time coming. The seed was planted in executive producer Kevin Williamson’s brain years ago, following the slasher flick “Scream 2” (1997), which he wrote and developed. After having an experience with an “overzealous fan,” he learned about the real-life Threat Management Unit, on which the work of “Stalker’s” Threat Assessment Unit is based.

The Threat Management Unit was formed following a number of high-profile stalking cases in California, including the death of actress and model Rebecca Schaeffer. In 1989, Schaeffer was fatally shot on her doorstep by Robert John Bardo, an obsessed fan who had been stalking her for three years and obtained her home address through a private detective agency.

Twenty-five years later, technology and social media have made it that much easier for stalkers to locate the objects of their obsession, and that’s a huge part of what Q hopes “Stalker” will address.

“With the advent of social media and us being so accessible, I think it’s smart to remind people to be more responsible with the information they provide,” the actress told “Access Hollywood.”

“Everyone can be a stalker,” Williamson added during the summer Television Critics Association media tour. “Everyone can be a victim. It’s a very complex show. We are making an entertaining show, but I do also hope to raise awareness.”

Be prepared: that awareness will freak you out big-time. The pilot episode is definitely reminiscent of Williamson’s work on the “Scream” franchise. A preview shows a young woman getting burned alive in her car by a masked and hooded man who has just made a menacing call to her phone. Sound familiar?

Q insists that while the show contains violence, it’s not gratuitous, but merely a reality of the subject matter. “Violence is really a bi-product of the story we’re telling,” she said in the TCA media tour session.

Still, you may be sleeping with the lights on for the next little while.

Slasher elements aside, "Stalker" promises to be a real eye-opener in terms of what can potentially result from oversharing on social media. There's something to be said for exercising one's right to privacy after all. Catch the series premiere of the suspense thriller Wednesday, Oct. 1, on CBS.
