Dude Bro Party Massacre III

Delta Bi member Brock Chirino talks to his therapist about the multiple slasher-related attacks on his fraternity because of their pranks. As result of these pranks, a sorority house mother was trapped in a burning building and vowed revenge on them. The mother goes on a rampage and kills most of Delta Bi. Brock and his friend Samzy manage to kill the mother, only for her daughter to cut off her face and use it as a mask, taking up the name Motherface.

Motherface begins her own rampage, killing more of Delta Bi. Eventually, Brock lights Motherface on fire and kills her. In the present day, the therapist grabs a pair of scissors and, revealing herself to be the new Motherface and the previous Motherface’s sister, slashes Brock’s throat. Brock’s brother Brent joins Delta Bi while trying to discover his brother’s killer. He befriends a crippled Nedry, Samzy, Derek, Todd, and his girlfriend Samantha, Turbeaux, who is scared of dogs, ZQ, Sizzler, Turtleneck Bro, Flannel Bro, and a beer addicted Spike. During a prank, Nedry and Brent accidentally cause a plane crash. Because of the plane crash, Dean Pepperstone sends Delta Bi to the lake house. After they leave, Motherface stabs Pepperstone to death.

Delta Bi meets with the river raft salesman, Paddy, whose family died during a flood caused in the past by Delta Bi. Delta Bi gets the rafts and leaves behind Nedry. They arrive at the house and begin to clean it up. Motherface spies Paddy on a raft and almost shoots him with an arrow, only for Paddy to commit suicide by shooting himself through the mouth. Motherface cuts the power, and Delta Bi sends Derek to fix it. Motherface rams a hoe into the back of Derek’s head, pushing it into the circuit and electrocuting him to death. Later at the house, Brent goes into the attic and finds Samzy, who tries to dance with Brent, only for Brent to accidentally drop Samzy’s head on the floor, snapping his neck. Motherface then ambushes Spike, trying to find more beer, and kills him by stabbing him in the head with a beer tap and draining his brains. She also makes him drink his own blood.

Samantha and Todd have sex in a tent before Motherface stabs Todd through the tent with a machete. Samantha is oblivious and falls asleep. ZQ and Sizzler go into the woods, and a tree crushes ZQ before Motherface bisects him. The next day, Delta Bi finds ZQ’s corpse and runs into the house, with Turbeaux knocking out Samantha with a baseball bat. Samzy reveals that he has a robot duplicate in the attic, but Brent realizes that he has killed him. Motherface throws his head through the window and uses a device to make Samzy rip out his tongue by the lake before drowning him. Motherface then rips out Sizzler’s heart and flushes his insides down a toilet.

Turbeaux is locked in a room full of dogs and uses a gun to shoot himself. Samantha finds Sizzler’s body and reveals to Brent that Todd impregnated her before Motherface appears behind her with a fire poker and stabs her through the stomach, killing her child. Motherface then pulls the poker up, vertically slicing Samantha in half. Brent finds a badly wounded Flannel Bro and Turtleneck Bro in the woods before Motherface stabs both of their heads with a javelin. Motherface attacks Brent with a tomahawk, but Nedry saves him, only for Motherface to throw a tomahawk into Nedry’s head, killing him. The spirits of all the dead Delta Bi strengthen Brent, and he uses the power to beat Motherface to death.
