Wilderness
The film starts with the arrival of Callum at a small juvenile facility ran by Jed and consists of Steve, Blue, Jethro, Lindsay, Davie, and Lewis. It is implied that the group gives Davie and Lindsay a hard time. After Steve and Louis get back at the two by urinating on them, Callum discovers Davie has killed himself. Davie's dad learns about the suicide and the group, along with Jed, are sent to an island. Once arriving, the group notices something odd about it.
Callum is knocked out by an unseen force and is discovered by the group. They go swimming and afterwards Jed notices a campfire in the distance. Lindsay is captured by an unseen force. They then meet a group of women, consisting of Jo, Louise, and Mandy. Jed and Louise come to agreement to keep the groups separate, while Jo and Lewis attempt to hit it off.
Steve and Lewis discover a man and chase after him. The man pokes Steve with a stick, prompting Steve to beat him with it, and Callum later discovers him dead. Callum is caught by Jed and Louise washing the blood off and is handcuffed by a tree. Jed blames the group for taking his phone which angers Steve. Jed then decides the girls are staying with them.
The next morning Jethro wakes up to go get more water and is then attacked by something. Jed orders Blue and Lindsay to go find him and they discover his arm in the water. The group is ambushed and Jed is killed by a group of dogs. One of the dogs chases Louise and she is knocked off a cliff.
The group discover Jethro hanging from a tree with the letter D painted on him. They find a cabin and take refuge in it. Lindsay reveals everything he knew, including who the killer is, which is Davie's dad. The next morning Blue is killed after he gets caught in a bear trap. Davie's dad then forces the rest of them out of the cabin.
The group finds that Louise is alive but badly injured. Louise is killed after the group leaves her alone. Steve plans to leave the others and Lewis agrees to it. They discover the fuel line is cut and Davie's dad shoots at them with a flaming arrow. The dogs return and they all get away from them. Steve and Lewis discover Lindsay and chase after him.
The dogs are eventually called back but one stays behind and Callum kills it. The group discovers Louise's head on a stick, prompting Callum to cut the dog's head off. They then cook the dog and eat it. Callum puts the dog's head on a stick. Steve and Mandy then fight the next morning.
Lewis subdues Steve and Steve calms down. Jo then angers Steve, prompting him to kill Lewis. Jo then runs away and is caught in a trap. Steve finds her and she begs him for help. He then declines and she is burned alive.
Steve runs into Lindsay and ties him to a tree. Davie's dad appears and forces Steve to cut his wrists. Steve then taunts him and throws a knife in his leg, only to be shot in the head with the crossbow. Davie's dad cuts Lindsay free and tells him to meet him by the boat. Callum appears and calls him out.
The two fight and Callum chases after Davie's dad with the crossbow. Mandy confronts Lindsay and causes him to fall off the cliff to his death. Callum prepares to shoot Davie's dad with the crossbow but the latter succumbs to his wounds on the sand. Mandy and Callum reunite and Callum states that "everyone died on the island". The two then get on the boat and leave the island.
