Satan’s Blade

Ruth and Trish rob a bank and murder two tellers, stealing $50,000. They escape to a snowy mountain cabin resort to wait for their partner George. The crime triggers an investigation as authorities close in on the getaway plan.

While holed up at the cabin, Ruth becomes greedy and shoots Trish to death. The violence shatters the already tense alliance between the former partners. Trish's demise foreshadows the danger lurking among the group's plans.

Ruth drags Trish's body as she moves, but an unseen assailant stabs her in the back. The attack leaves Ruth mortally wounded, collapsing before the others can intervene. The identity of the attacker remains unknown at this point.

Ben, the local sheriff, and another officer arrive at the cabin after gunfire is reported. They discover the corpses of Ruth and Trish and begin the investigation. The violent events at the cabin set the stage for what comes next.

The next day, two married couples arrive at the resort to celebrate Tony's graduation from law school and his passing the bar. The peaceful vacation atmosphere contrasts with the earlier killings. The new guests settle in, unaware of the danger still looming nearby.

At the same time, a group of college girls arrives with a friend whose father has recently died. Their carefree energy and chatter introduce a new dynamic to the resort. They also hear about the murders but decide to stay and continue their trip.

Despite warnings about a local legend and the earlier murders, the college girls opt to take the cabin next door to the couples. They dismiss the danger as superstition and press on with their plans. The stage is set for the deadly night to come.

During the night, one of the young women dreams of a man slaughtering her and everyone else. The nightmare foreshadows the impending violence that will invade their cabin. The eerie vision unsettles the group but does not deter their plans.

The following day, Stephanie encounters Tony on the lake, and the two talk. They end up spending the afternoon together while Stephanie's friends remain at their cabin. The budding connection becomes a focal point amid the lurking danger.

That night, an unseen killer enters the girls' cabin and systematically stabs each of them to death. The ruthlessness of the attacker devastates the group and escalates the suspense. Stephanie remains mostly unaware of the immediate threat.

Stephanie returns to the nearby cabin to find the others murdered; she hides under a bed as the killer breaches. The killer tracks her, but she manages to survive by staying quiet. The violent intruder continues through the night, forcing her to stay hidden.

The next morning, Deputy Sheriff Ski confronts Stephanie, embraces her, then stabs her in the stomach. He claims it was about money and that he was possessed, brandishing a talisman-like knife. The brutal confession reframes the killer's motive and hints at a deeper conspiracy.

The Sheriff arrives and reveals that Ski was the unseen accomplice of the bank robbers who appeared at the start. His double life confirms the initial crime's lingering reach. The revelation ties the two timelines of the film together.

A hand emerges from the lake and tosses the knife back out, its blade sticking in a tree. A hiker later notices the knife and dislodges it from the bark. The chain of violence lingers even as the investigation closes in.
