Suite Nothings, is a sleazy L.A. phone *fantasy* hot-line...in other words a phone-sex service, voiced by failed models, in which callers get to divulge their fantasies over the phone. Among them is Bobo, an individual whose twisted sense of humor, is matched only by his warped mental state. Dressed in an eerily comical mask of all things a clown, he begins murderous vendetta against these hot-line workers. As a body-count in this city steadily increases, this so-called ringmaster in his own personal circus of fear and fatal pain, who makes his victims walk a tightrope of sheer terror moments before he brutally ends their lives.

In the opening scene, a young actress, named Camille (Starr Andreeff), is interviewed for a job by Ruth Wilson (Karen Black), the owner of a telephone sex line. The timid Camille shocks Ruth with her lusty performance and is hired. She is welcomed into the fold by the other sex-line workers, including Barbara (Karen Mayo-Chandler), Jo Ann (Karen Witter), and Kristi (Lynn Danielson). Later that night, Jo Ann is jogging through a local park when a man wearing a clown's mask kills her with an oversized baseball bat, calling out, "It's time for Bobo!"
The next morning, Kristi awakens in the arms of her photographer boyfriend, Kevin Silvers (Cameron Dye). As they make love, another photographer, named Dennis (Geoffrey Lewis), watches from a nearby rooftop.
Across town, police discover Jo Ann's body. Lieutenant Frank Meyers (Tracey Walter) finds Kevin Silvers' business card on the corpse. Upon entering Kevin's studio, Meyers and his assistant, Lieutenant McDonald (Silvana Gallardo), interrupt Kevin photographing a nude Barbara. Meyers gets a bad feeling about Kevin and orders McDonald to investigate him.
At the sex line office, Barbara tells the girls what happened to Jo Ann. Camille is frightened and asks Barbara for a ride home. As they leave the building, they run into another tenant, accountant Dave Stringer (Bud Cort), who is drinking at a water cooler. When they attempt to sneak around him, a startled Dave spills water all over the two women.
After dropping Camille off, Barbara sees a clown in a car. She stops to let him pass, but he speeds up and smashes into her scooter, throwing her into a yard. Hearing the noise, the homeowner comes to investigate and the clown rams a shovel into the man's head, also killing him. Yelling, "It's time for Bobo!" the clown wraps a garden hose around Barbara's neck and strangles her to death.
Ruth Wilson receives a call at home asking her to come identify Barbara's body. When she hangs up, her daughter asks if the call was from her father, Dennis. Ruth informs the girl that her father has left for good.
The next morning, LAPD Lts. Meyers and McDonald arrive at Kevin's apartment to inform him of Barbara's murder. Kevin introduces Kristi, who confirms she was with Kevin all night. She admits it would be easy for a caller to find the sex line office and follow a girl home. When the policemen leave, Kristi asks Kevin where he was last night after covering for him and lying to the police. He insists he was home alone.
Later, Kristi confronts Kevin with information Meyers gave her about Kevin getting arrested a few years ago for beating his former girl friend. A drunken Dennis arrives and accuses Kevin of taking over a photo shoot that he had been scheduled to do and ruining the negatives for another of his magazine assignments. Kevin throws Dennis out of the office. Ruth hears of the fight and visits Dennis in his filthy studio apartment to discover head shots of the dead girls. Dennis admits he stole them to get Kevin in trouble, and Ruth warns him to stay away from her, their daughter, and the other girls.
The next day, Ruth, Kristi, and Kevin talk to the wife of the homeowner who was killed. On the lawn, Kevin finds a large sliver of glass from a car mirror.
Ruth returns to work to find Meyers and McDonald outlining a plan to lure the killer to the office. All incoming telephone calls will be re-routed to the girls' homes. The girls will drop hints about the office location, and when the murderer shows up, Meyers will grab him. Camille volunteers to act as bait.
On the night of the sting, a police officer stands outside Camille's door. Bobo the clown calls from a telephone booth and describes Camille's features. Camille looks outside, but the cop is gone. Bobo, who used a tape recording to make police think he was still on the telephone, leaps from behind Camille's couch and strangles her with the telephone cord. Police arrive to find both the police sentry and Camille dead.
Meanwhile, Kevin drives Kristi to the office. She looks in the car's side mirror to apply lipstick and notices it is missing a sliver of glass. Kevin and Kristi stake out the parking lot to see Dave Stringer get into the car. After charming a janitor into giving her the key, Kristi enters Stringer's office. As she lets Kevin in, she trips on a power cord, which turns on a lamp. Down the street eating a hot dog, Stringer sees the light and runs back to his office. Kristi meets him in the hall and delays him long enough for Kevin to duck into Stringer's closet. Later, Kevin and Kristi hide in a seedy motel and make love. In the next room, a hooker is beaten to death with a bottle.
The next morning, a hotel clerk (Paul Bartel) spots bloody water seeping under the motel room door. He enters to find the hooker's bloody corpse in the tub with the water running. Kevin and Kristi wake up to find the motel swarming with cops. Meyers and McDonald arrive on the scene where they briefly talk with the portly Detective Langella (Divine) who has already arrived and is discussing the crime scene with the forensic techs. Kevin and Kristi get away by sneaking out a bathroom window.
That night, Kevin gives Kristi a pistol for protection and tells her to meet him at the office. As he leaves Kristi's building, Kevin is arrested by Meyers and McDonald, who interrogate him at the police station. Kevin uses his one telephone call to contact Kristi. He asks her to break into Stringer's office to find evidence that he is the killer. Kristi once again breaks into Stringer's office and turns on the light. Stringer sees it from across the street and runs back in time to find Kristi open a box containing human nipples. Kristi punches him in the face and runs out of the building. Stringer follows, but is fatally struck by a car. When the police arrive on the scene, they also conclude that Stringer was the killer and close the case.
A few days later, Kevin and Kristi take a trip to a cabin in a secluded valley north of Los Angeles. While looking for blankets in Kevin's car, Kristi discovers a clown mask. She puts it on and confronts Kevin. He takes out a pistol and tells Kristi that he used to be a professional clown until all the other circus performers were murdered. He hands Kristi the pistol and tells her to shoot him if she no longer loves him. When she refuses, Kevin suddenly turns into Bobo.... thus revealing that he has Dissociative Identity Disorder, and that he really did kill all of those women under his 'Bobo' personality, as well as framed Stringer for the killings. Kevin/Bobo begins to strangle Kristi with his belt. She breaks away, grabs the gun, and shoots Kevin in the chest. Thinking Kevin is dead, Kristi telephones the police. As Kristi waits, the killer dons the clown mask and pulls the gun from Kristi's hands. Lt. Frank Meyers appears and blasts Kevin/Bobo with a shotgun, killing him at last.
