Craig, a talented auto mechanic, finds himself facing a pivotal moment in his life after losing his job and facing financial struggles that threaten eviction. Just as despair begins to set in, he unexpectedly encounters an old high school friend, Vince, at a rundown bar where they reminisce over a few drinks. Their bittersweet reunion is interrupted by the appearance of a seemingly kind couple, Colin and Violet, who appear to offer them help, but their generosity comes with strings attached—a series of escalating dares in exchange for financial rewards.
The night kicks off with a drinking contest, leading to a chain of dares that grow progressively more dangerous and lucrative. Craig's luck takes a turn for the worse when he finds himself brutally beaten by a bouncer while vying for a mere $500. Upon regaining consciousness, he discovers he’s in the lavish home of Colin and Violet, where tension begins to brew between him and Vince.
As the friends dive into increasingly ridiculous dares, such as a breath-holding contest that spirals out of control, it becomes clear that winning isn't solely about money; they're also vying for Violet's attention on her special day. Vince's determination grows darker, resulting in underhanded tactics that leave Craig feeling betrayed.
With the stakes now perilously high, Vince learns of the couple's true wealth—a staggering $250,000, tantalizingly within their reach. As they devise a plan to steal the cash, the situation escalates. When Vince's knife hovers dangerously close to Colin's throat, Colin reveals that the safe had never been locked—just part of the game. The couple's unexpected prowess in martial arts and weaponry becomes evident, leaving Craig and Vince vulnerable but not without an opportunity to negotiate.
The game takes a shocking turn when Craig is compelled to engage in an inappropriate act with Violet for a payout of $4,500, just what he needs to cover his overdue rent. This unexpected requirement pushes Vince over the edge, straining their friendship further. Craig's guilt about cheating on his wife begins to surface, leading him to withdraw, but Colin seizes the moment to entice Vince with a horrific proposition: severing his pinkie finger for $25,000. Just as Vince considers the gruesome dare, Craig chooses to offer himself up for a lesser amount.
In a jaw-dropping twist, Craig's decision leads to him losing his pinkie finger, resulting in Vince spiraling deeper into anger and frustration. As tensions mount, both are forced to confront their darkest fears, culminating in a grotesque challenge involving a cooked dog. The prize for victory? A staggering $50,000. In a nail-biting moment, Craig manages to win, but his elation is short-lived as Vince unleashes his fury, resulting in a brutal confrontation.
Colin's intervention attempts to mitigate the swelling chaos but instead drives Vince toward a dark decision: eliminate Craig for the prize money. Torn, Vince's internal conflict breaks through as he struggles with the prospect of betraying his friend. At last, he spares Craig's life, urging him to leave. However, their fragile alliance shatters when Craig retaliates, leaving Vince incapacitated.
What follows is a shocking reveal: Colin pays off Violet's bet, which had secretly favored Craig to eliminate Vince. As the dust settles, Craig emerges with his hard-won cash but ultimately faces a bittersweet reunion with his family. Just as the air of triumph envelops him, his wife's sudden reappearance, her gaze locked on the bloodied mess around them, shatters the fleeting sense of relief.
