Highlights
Jas visits her sister Laura in England for an adventure trip. They go to a remote cabin and later encounter a group of perverted men led by Randy. Laura refuses Randy's advances, and the sisters leave. Jas reveals she's in an abusive relationship and has started self-defense classes. Laura gives Jas a necklace that belonged to their dad. Jas leaves for town to buy drinks, leaving Laura alone at the cabin.
The group of men returns to the cabin and forces their way in. Laura tries to protect herself, breaking Randy's nose and stabbing another man, but Randy shoots her in the head. The men leave one of their own, Kent, to dispose of the body, but Jas returns and discovers Laura's lifeless body. She then kills Kent and vows revenge against the culprits.
Jas sharpens a knife, drags her sister’s body, puts on the necklace, and gathers weapons before driving away. She finds Randy and his men inspecting stolen items. Randy's men are worried about the situation and the unresponsiveness of Kent. Jas ambushes and kills a man with garden scissors, then uses a chainsaw to brutally kill three other men in a barn while Randy remains oblivious. Randy eventually discovers his dead men and flees.
Randy meets up with three other men, Lewis, Dave, and Charlie, and they drive away, unknowingly followed by Jas. They discover Jas's car, Randy finds her passport, and they slash her tires. Randy reveals he told his boss, Jacob, about the girls. Jas, hiding in the woods, makes a noise, alerting the men. Randy attempts to manipulate Jas, but she strikes him with a rock and flees. Jas eventually overpowers Lewis, knocking him out.
Jas's car tires are slashed. The thugs return to the cabin but find no bodies. Jas, exhausted, uses Laura's running techniques to continue. She sneaks up on the men, knocks out Dave, and holds the others at gunpoint, but Lewis ambushes her from behind, knocking her out. Jas wakes up tied, but manages to free herself using a small knife. She pretends to be unconscious, then attacks Lewis when he tries to assault her.
Dave and Charlie come to check on Lewis. Jas kills Lewis, then stabs Dave, sending him down the stairs. She fights Charlie, eventually gouging his eyes and strangling him. An injured Dave shoots Jas in the shoulder and brutally beats her, but Jas retaliates with an elbow and then kills him with an alarm clock. Exhausted, Jas hears Laura's voice, giving her the strength to remove the bullet from her shoulder.
Randy returns with his creepy boss, Jacob, and three other thugs. Jacob and Randy enter the house and find their men gone. Jas traps them in a room filled with gas, preventing their escape. One of Jacob's men enters the house and is brutally killed by Jas. Jas disarms the remaining two thugs downstairs, engaging in a fight, while Jacob manages to escape the gas-filled room, leaving Randy unconscious. Jas kills the two men downstairs.
Jacob tases Jas from behind and tries to drag her away with a chain around her neck. Jas resists, fights back, uses the taser on Jacob, and shoves his head into a sink. Randy arrives, accidentally shoots Jacob, and pursue Jas. Jas gets into a car, runs Randy over, and then shoots him. Randy tries to fight back, brutally beating Jas and taunting her. Overwhelmed by memories of Laura, Jas uses her sharp necklace to stab Randy. She then sets his body on fire. The next morning, Jas sits by Laura's body, wearing the necklace, mourning her sister.
