Hannah reluctantly agrees to go to a party hosted by Jessica one night in hopes of seeing Clay, her crush. She ends up alone after drinking too much at the end of the night, and Sheri offers to drive her home since she's going that way anyway. Sheri swears she's good to drive, but crashes into a stop sign while digging around in her purse for a charger for Hannah's dead phone.
The stop sign falls over, and Hannah tells Sheri they have to alert the police, otherwise someone could get into an accident. Sheri refuses, scared that it will ruin her future, and drives off without Hannah. Hannah runs to a nearby convenience store to find a phone and call the cops, but it's too late — their classmate Jeff (one of Clay's close friends and an all-around sweetheart) dies at that intersection because of the missing sign. Hannah blames Sheri for the constant guilt she carries around afterward.
