As snowflakes gently fall upon a picturesque cabin tucked away in the woods, the air is alive with an expectation of joy as Alex (39), a playwright turned lawyer, eagerly welcomes his youthful bride, Alice, who is five years his junior. Their three couples join them in this cozy retreat to celebrate New Year's Eve, setting the stage for an unforgettable night. The first to arrive is Don, a fellow lawyer, accompanied by his wife, Lynn. Unfortunately, they come bearing festive hats but forget the essential wine. As Lynn boasts about her recent professional achievements, it casts a shadow over Don's struggles, forming a backdrop for their conversation as she chats with Alice in the kitchen.
Meanwhile, outside, the men gather around the barbecue, swapping tales and laughter. Don pitches his latest entrepreneurial idea, "The Naked Maid" cleaning service, drawing roars of laughter from his friends, particularly around his old Jeep, which seems to demand constant repairs due to his lack of alternatives.
As dinner time draws near, a tender moment takes place when Alice pulls Alex aside to express her insecurities, asking, "Do I look okay?" To which he replies reassuringly, "You look amazing," a reminder that their relationship is still a delicate balance. However, as the night progresses, it becomes apparent that vodka isn’t the only issue lurking under the surface of Don and Lynn's marriage.
A twist occurs when Eve, another couple, calls to announce her arrival with Helena, "the bridesmaid from the wedding," which adds to the evening's dynamic. As laughter and wine flow freely, Don and Lynn retreat, while Alex stays outside with Nick, who shares the pain of his recent breakup.
As the celebration heightens, the men ambush a game of backgammon. Nick's curiosity about Helena leads to a confrontation when he implies that Alex had feelings for her during his relationship with Alice. Alex’s rebuttal, "Will you keep it down... No, I didn't," underscores the tension bubbling under the surface. The night drifts to a close with secrets hanging in the air like the dying embers of the fire.
The following morning ushers in a palpable tension as the breakfast table buzzes with strained conversations. Eve, visibly pregnant, and Steven, a polished lawyer, arrive with Helena—a striking British model—and the atmosphere thickens as both Alex and Nick find it hard to maintain eye contact. Lynn asserts her authority, demanding Don go fetch supplies despite the cabin being stocked.
As the group scatters into the snow-laden scenery, Alice and Eve meander through the idyllic landscape, while Alex, Nick, and Steven embark on a hike. Meanwhile, Lynn takes a mid-morning nap, leaving Helena in solitude to lose herself in a book.
While Alice and Eve's conversation shifts to family planning, Nick opts to stay behind in the cabin, longing for a connection with Helena that he fails to ignite. Later, Alex approaches Steven for career advice but is met with discouragement based on his background.
Reunited at the cabin, Alex confides in Alice about his disdain for Steven, calling him a "douche-bag," a sentiment that resonates with her. The others venture out into the snow, leaving Alice and Alex behind, where he finds himself entranced by Helena's beauty as she emerges wrapped in a towel after a bath, an encounter that sends Alice into emotional turmoil.
As the festivities escalate into wild abandon, Nick courageously pursues Helena, only to face rejection, with her rebuff echoing painfully in his ego. Inside, Alex’s attention is seized by the sight of Alice and Helena dancing joyfully, but Lynn attempts to disrupt this moment, directing Don on yet another errand.
The tide of the night shifts when Eve finds herself stranded at the store with Alice due to a dead battery. Back in the cabin, Alex’s pent-up frustration begins to boil over, creating an atmosphere rife with tension as his friends try to calm him down. Just as a confrontation seems unavoidable, Nick steps in with his calm demeanor, and they engage in a release of heartfelt confessions. Through exchanged apologies and Steven’s tempered admonition, the group is reminded of their capacity for forgiveness and personal growth.
As the clock strikes midnight, a spectacular display of fireworks lights up the sky, a breathtaking ode to life's unpredictability. With Eve and Alice returning to the cabin, Alex and Alice retreat into their sanctuary, where they find comfort and solace in each other's embrace, a beacon of love amidst the chaos unfurling around them.
