The film begins with the peaceful settlement of a group of characters - Sam, a sexually explosive estate agent, Melody, a frustrated French artist, Fred, a shy and excitable young man, and Anthony and Kate, a happily engaged couple. They are living in an asbestos-filled house surrounded by abandoned X-ray machines, all settling into their new lives.
However, when Lulu - Anthony's oldest and least responsible friend - unexpectedly arrives, everything changes. Lulu is a troublemaker, always causing chaos wherever she goes. She brings her own problems with her, including a flirtatious relationship with Sam, which leads to a series of misunderstandings and tensions between them.
Melody also finds herself drawn to Lulu's charms, leading to more conflicts within the household. Meanwhile, Fred struggles to adjust to his new surroundings, feeling out of place amidst the asbestos and abandoned X-ray machines. He also becomes increasingly irritable and excitable, often acting impulsively.
As the film progresses, Lulu's arrival causes further disruption in the lives of everyone in the household. She creates havoc with her constant need for attention and attention-seeking behavior. The tension between Sam and Lulu escalates, leading to a physical altercation that leaves both of them injured.
Meanwhile, Anthony and Kate try to maintain their relationship while dealing with the stress of Lulu's arrival. Their relationship takes a strained turn when Lulu tries to steal Kate's engagement ring, causing a major argument between them.
Despite the challenges they face, the characters manage to find some semblance of normalcy in their lives. Sam and Lulu eventually reconcile, and Lulu starts to fit in better with the rest of the family. However, the tensions continue to mount, and it seems like nothing will ever truly be resolved.
In the end, the film ends on a note of uncertainty, as everyone continues to navigate their way through the chaos that Lulu has brought into their lives.
