Listen (1996)

In Listen (1996), San Francisco ad exec Sarah (Brooke Langton) moves into the apartment complex where her boyfriend Jake (Gordon Currie) also lives. Upon arriving, Sarah discovers that her mobile phone enables her to eavesdrop on the conversations going on across every other phone line in the building. She and her buxom buddy Krista (Sarah Buxton) get hooked on hearing their neighbors' secrets—until they become embroiled in murderous intrigue. With kinky sex and a kooky lesbian, Listen is one erotic thriller to keep an ear out for.
