Texas bartender Ray and housewife Abby navigate a torrential nighttime downpour, discussing Abby's troubled marriage to Ray's boss, Julian Marty. Their emotional turmoil culminates in a passionate rendezvous at a motel. However, unbeknownst to them, private detective Loren Visser captures their intimate moments on film and delivers the incriminating evidence to Marty. When an ominous caller alerts the couple that they are being watched, Abby hastily gathers her belongings, including a gun gifted by Marty.
In a tense confrontation at the bar, Ray demands his unpaid wages from Marty, who chillingly warns him that Abby will betray him just as she did him, stating, > "I haven't done anything funny." Following a failed kidnapping attempt on Abby, Marty hires Visser, offering $10,000 to eliminate both Ray and Abby, nonchalantly instructing him to "go fishing" and he'll receive a call when the job is completed.
Visser breaks into Ray's home, pilfering Abby's gun before showing Marty staged photographs of the supposedly deceased couple. As Marty vacillates between shock and greed, he secures a photo in his safe while retrieving the cash. In a shocking twist, Visser uses the gun to shoot Marty before haphazardly fleeing with the money, oblivious to leaving behind his lighter.
Contrary to assumptions, Visser manipulated the photos to portray Ray and Abby's non-lethal slumber as death. When Ray uncovers Marty's barely alive body, he inadvertently discharges the gun, leading to a chaotic struggle. With empty chambers echoing the tension, Marty futilely attempts to shoot Ray, who ultimately decides Marty's fate by finishing the burial.
As Ray tries to assure Abby, insisting he "cleaned it all up," she eerily paraphrases Marty's earlier words, igniting an argument. Following a cryptic phone call from Visser, Abby suspects a wider conspiracy—believing it to be Marty calling. Amidst the chaos, bartender Meurice conveys a message from Marty about stolen money, which hints at the ruse behind the $10,000.
While destroying the falsified images, Visser realizes he left a critical piece of evidence behind and attempts to access the safe, only to be interrupted by Abby. In a sensational turn of events, Abby, plagued by a nightmare featuring Marty's warning of impending doom, confronts Ray about his actions surrounding Marty’s grave.
In a desperate bid for survival, Abby takes heed of the dangers around her, only for tragedy to strike as Ray is shot by Visser from a hidden vantage point. Abby, now entangled in a life-or-death struggle, ingeniously hides and then fights back, ultimately pinning Visser with Ray's own knife. In a gripping exchange, she shoots through the bathroom door, asserting her newfound power and resolve, saying, > "I'm not afraid of you, Marty," to which an injured Visser manages to chuckle, replying, > "Well, ma'am, if I see him, I'll sure give him the message."
