The story begins with the discovery of a lost cell phone in front of the protagonist's doorstep. The phone belongs to a girl named Anna, and the protagonist's mission is to return it. However, unlocking the phone proves difficult as it requires a password, which is eventually revealed to be "1807," the birthday of Anna's cat Tobias, not her dog Toby as initially assumed.
As the protagonist explores Anna's phone, they find a disturbing video recorded by Anna herself, where she pleads for someone not to find her. This raises suspicions that Anna might be in danger. They also uncover her relationship troubles, including a cheating ex-boyfriend named Greg and a co-worker named Murv who harasses her.
Further investigation reveals that Anna stopped communicating with her best friend and mother around August 13th, which coincides with the last selfie she took. The protagonist also discovers that Anna worked for a company called Faraday Safety, where her boss, Tim Faraday, appears to be a problematic figure.
They attempt to reset Anna's Twitter password, uncovering the version of her phone's operating system, IRIS Applesauce. The protagonist then contacts Greg, who behaves suspiciously but doesn't reveal much.
Next, they communicate with Taylor, who seems to know Anna and mentions that "finding girls is the whole point of Tinder." This suggests that Anna might have moved on from Greg. However, Taylor asks a distressing question: "Did she kill herself?"
The story is filled with suspense and hints at a complex mystery involving Anna's disappearance, her troubled relationships, and the strange video she left behind.
