The Exit Tapes follows 23-year-old Adrian Morsen, who was left a box of cassette tapes from his deceased Uncle in his will. These tapes detail his uncle Robert, a freelance journalist undercover, investigating a tech company called APEX after receiving an anonymous letter the company was hiding something. Adrian soon has two unwelcome intruders on his Twitter account: one following him and trying to prevent his uploads, the other seeming to want to help. Recently, the tapes were stolen from his home, and one of the intruders is taking it upon itself to retrieve the tapes for him and return them so Adrian can continue his work. Who these intruders are is a mystery, as is the reason as to why one is helping him.
