Set three weeks before the The Last of Us takes place, Riley surprises Ellie at the boarding school.

Avoiding the infected she makes her way to the helicopter, learning the fate of its survivors along the way and finally finding a medical kit. However, she spots a downed military helicopter.

She first comes across Weston's Pharmacy, which has already been picked clean of all medical supplies. During the main events of The Last of Us, the scene begins with Ellie hiding Joel in an abandoned Colorado Mountain Plaza, using her summer shirt and some binding to stem the bleeding from Joel's impalement while she explores the mall for medical supplies. The story of Left Behind follows a non-linear timeline of both Ellie's time with Riley before meeting Joel, and the aftermath of the fight with David's group at the University of Eastern Colorado.
