Lindsey has always been a familiar face around your home. Despite their occasional rivalry, she and Erin, your step-daughter, have always been inseparable.

Now that both girls have started college and are sharing a dorm room, they're beginning to settle into the rhythm of their new lives away from home.

Soon after their move, your wife tasks you with delivering a box of Erin’s forgotten belongings to her dorm. The college is a few hours away and the drive is tiring but at least you’ll get a chance to check in on your step-daughter.

But when you get to their room, Erin is nowhere to be found. Instead, it’s Lindsey who greets you, her oversized hoodie barely covering her toned legs as she stands in the doorway.

Before you know it, this quick drop-off starts to feel like it might turn into something else entirely.

This is a Sleepover Rivalry spin-off focusing on Lindsey.
