I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Gone Movie plot: Jill Conway is a young Portland woman who lives with her sister, recovering alcoholic Molly. One year prior, Jill was kidnapped by a serial killer who abandoned her in a hole in the forest, where she found human remains. When her abductor descended into the hole to kill her, Jill was able to stab him with a bone and climb his rope and return to civilization. However, the police didn't find the hole and discovered that Jill had been committed to a psychiatric institution for several years after her parents' death. Believing that the abduction only happened in Jill's head, they closed the case.One day, after returning home from work at a local diner, where she and her friend Sharon Ames are generously tipped by a regular customer about to move out of town, Jill finds Molly gone and is unable to reach her boyfriend, Billy. Knowing that Molly wouldn't leave the house with Jill absent and that she had an important test the following day, Jill becomes convinced that the man who took her has now captured Molly and heads to the police station to ask for help, but Sargent Powers and Detective Erica Lonsdale dismiss her claims and promise to look into the case after a few days, but Jill claims it will be too late then. Before she leaves, newcomer Detective Peter Hood pulls her aside and tells her he believes her, giving Jill his card in case she needs help.Billy calls Jill and tells her that he hasn't heard from Molly, and that she didn't show up at the exam. Jill interrogates her neighbors and finds out a van with a locksmith's name parked in front of her house in the middle of the night and honked several times. Using the neighbors' description of the van, Jill finds the company it belongs to and heads there, where she questions the van's driver - who is also the company owner's son - about Molly's whereabouts. He claims to not know anything about it, and Jill feigns leaving in order to break into the van, where she finds a receipt for a hardware store and duct tape. She holds the driver at gunpoint and forces him to... My question: What is the name of the stranger that rents the van?
