“Sirens,” premiering Thursday on Netflix, is an odd sort of a series, an interesting mix of hifalutin ideas, family drama and what might be called dark farce.

Set over Labor Day weekend on a Cape Cod island peopled by rich folks whose taste runs to pastels and floral prints, it stars Julianne Moore as Michaela, formerly a high-powered attorney who has given that up for marriage to hedge-fund billionaire Peter (Kevin Bacon) and a life dedicated to rescuing birds of prey. The queen of all she surveys, she speaks in moony aphorisms, is posing for Vanity Fair and orchestrating a fundraising gala, among minor entertainments.

Meanwhile, in Buffalo, we meet Devon (Meghann Fahy) a working-class hot mess, making her entrance out a police station door, wearing a short black dress, looking the worse for wear. Struggling to care for her father Bruce (Bill Camp), diagnosed with dementia, she goes in search of her sister, Simone (Milly Alcock), who has been working as Michaela’s personal assistant. After traveling 17 hours — carting, for reasons of comedy, the giant edible arrangement Simone has sent in lieu of an actual response to her call for help, still wearing her night-in-jail clothes — Devon will discover that her sister has been transformed: She’s removed the matching tattoos they got together, had a nose job and presents as something like the Disney version of “Wonderland’s” Alice, minus the curiosity. (“You’re dressed like a doily,” says Devon.) Ingmar Bergman fans will note the meant-to-be-noted crib from “Persona,” underlining Devon’s observation that Simone loses herself in other people.

Simone, for her part, is delighted that she gets to call Michaela “Kiki,” “which is really a special honor,” and faithfully amplifies Michaela’s mercurial requests to the staff, personified by Felix Solis’ Jose, who hate her. (They maintain a text chain to joke about her.) For all that she’s loyal to Michaela, and considers her a best friend, she’s been hiding both her working-class roots and the fact that she’s been sleeping with Ethan (Glenn Howerton), Peter’s also-rich pal and neighbor.

Though Michaela worries he might be having an affair, Peter, for his part, comes across as an essentially good guy, for a hedge fund billionaire. He’s friendly with the help, who worked for him before his marriage to Michaela — there are a first wife and adult children offstage — can cook for himself and hides away from the pastel people in the mansion’s tower, where he strums a guitar and smokes a little pot. But room has been left for surprises.

“Sirens” is the sisters’ shared special code for “SOS,” which seems less practical than, you know, SOS, but ties into the vague Greek mythological references with which the series has been decorated — more suggestive than substantial, I’d say, though it’s possible that is my lack of classical education showing. The house Siri system is called Zeus. One episode is titled “Persephone,” after the goddess of the dead and queen of the underworld; Simone does indeed say to Michaela, “You are literally a goddess” — she does dress like one, in flimsy, flowing gowns — while Devon thinks that something’s gone dead behind Simone’s eyes, that she’s been zombified: “You’re in a cult.”

It was the sirens’ sweetly singing, of course, that drew sailors to their deaths in the old tales, and at one point Michaela looks out over the ocean and muses on the boats of whalers crashing bloodily on the rocks. (She is particular about the blood.) There is, in fact, a sailor in the series, Jordan (Trevor Salter), who captains Ethan’s yacht and whom Devon picks up in a hotel bar, but he is perhaps the least likely character in the show to crash into anything. And Michaela is attended by a trio of women (Jenn Lyon as Cloe, Erin Neufer as Lisa and Emily Borromeo as Astrid) who, suggesting the title creatures, speak in harmony and act as one, but they are more the embodiment of a notion, a throwaway joke, than active participants in the story. Michael Abels’ score features a choir of female voices, opts for something that one might well identify as ancient Greek music even with no notion of what ancient Greek music might have sounded like.

The core of the series is the struggle between Devon and Michaela for the soul of Simone, though there are ancillary battles that will help decide the fate of the war. For a viewer, it’s natural to side with Devon, who, after locking horns with Michaela, will go undercover at the mansion, dressing according to the house rules while she pokes around. (There is the suggestion of a murder mystery.) However hot a mess she may be, she isn’t pretentious; she has energy, boldness and consistency, and whatever she gets wrong, she lives in the world that most of us do. (I am assuming you are not a billionaire with a mansion on a cliff, a birdhouse full of raptors and a large staff to tend to your needs and whims, but if you are — thanks for reading!) That isn’t to say that Michaela doesn’t have her troubles — indeed, her neediness, which expresses itself as caretaking, resembles Devon’s. “I take care of everything in my orb,” says Michaela, “big and small, prey and predator.”

I hadn’t known when I watched “Sirens” that it was based on a play, the 2011 “Elemeno Pea,” by Molly Smith Metzler, who created the series as well, but I thought it might be. It had the scent of the stage in the way characters — including Bruce and Ray (Josh Segarra), Devon’s boss and adulterous occasional hookup — kept piling in, along with its farcical accelerations, its last-act revelations and reversals.

At “only” five episodes, it stays more focused than most limited series, though the tone shifts a bit; some characters come to seem deeper and more complex, which is good on the face of it, but also can feel a bit manufactured. Some bits of business are planted merely to bear practical fruit later. The ending I found half-satisfying, or half-frustrating, from character to character, but there are great, committed performances along the way, and I was far more than halfway entertained.
