Build a movie plot around this: What did the Robertses tell the detectives? Brad was disturbed.
The film begins with Detective Havenhurst driving with his partner Detective Vargas. They receive a call and drive to the scene of a murder. As they push their way through the crowd at the crime scene, they see Brad McCullam leaving with a coffee cup. Inside the house, the detectives find the body of Mrs. McCullam, Brad's mother, who has just been stabbed with an antique sword. At the scene are the neighbors and chief witnesses, Mrs. and Miss Roberts. The detectives soon realize that they had just seen the murderer leaving the scene.The Robertses tell the detectives that Brad was disturbed, and had changed when he went to Peru recently. In a flashback we see Brad in Peru preparing for a kayak trip on a raging river. Back to the present time, the police have learned that Brad has taken two hostages in the house across the street. The police surround the house, and Brad's fiancee Ingrid arrives. Ingrid talks to Havenhurst about Brad's trip to Peru, saying that Brad's friends all drowned on their kayak trip, which Brad had decided at the last minute not to take part in; he later claimed that the voice of God had told him to stay behind. Several more flashbacks follow of Brad and Ingrid in Brad's bedroom, talking with Mrs. McCullam, looking at nearby houses, having dinner. Back in the present, Brad demands pizza for himself and the hostages, along with a car for transportation to Mexico.In another flashback, we see Brad in rehearsals for a Greek tragedy directed by Lee Meyers. As the pizza is delivered to Brad, Lee arrives at the scene of the crime. Lee talks with Havenhurst about Brad, and we flash back to Lee and Brad visiting Uncle Ted's ostrich farm. Brad convinces Uncle Ted to give him the antique sword which would be used in the crime. Brad uses the sword in more rehearsals for the play, in which he plays the part of a man who kills his mother, who is played by his fiancee Ingrid. Brad becomes disruptive and is eventually kicked out of the production, but still travels to Calgary with Lee and his mother...
