For many, Los Angeles is the city of dreams: an oasis of palm trees, fast cars and success. But for others, like ambitious young architect Walter Woods, who has been hired to design a Beverly Hills mansion for a wealthy new client, the dream can literally turn into a nightmare. Convinced his career is about to take off, he speeds along the highway unaware of the disastrous and violent turn of events that will change his life, or end it altogether. Along the way, Walter narrowly avoids a high-speed collision with a maniacal truck driver, and arrives at his new apartment to meet an oddball assortment of residents. His new neighbors include a beautiful hooker, an East German comedian and a cranky building manager who is as lazy as he is grumpy. A series of strange, unexplained events soon begin to unravel the normally calm and collected Walter. These minor nuisances quickly escalate into perilous and terrifying encounters with a mysterious stalker, and as things turn 'deadly' he is pushed to breaking point. With the police in pursuit, Walter confronts his vicious attacker in a fight not only for his sanity, but also for his survival.
