Ghostline (2015)
Plot: Life for a couple, Tyler and Chelsea, takes a terrifying turn after they move into a new home just outside of Los Angeles. They begin to receive a series of increasingly menacing phone calls on their landline from a woman who insists that Tyler is her ex-boyfriend, Eric. When they try to investigate, they learn the calls are coming from a "ghostline," a connection with no traceable number or location, suggesting a supernatural disturbance. As the mysterious caller and poltergeist activity escalates in violence, the couple enlists the help of police and paranormal investigators, eventually uncovering the backstory of a woman named Ellen who suspiciously disappeared after last being seen with a man named Eric. The couple is then forced to take desperate and deadly action to end the haunting.
