Cain Rose Up (2018)

It is the last few days of college for student, Kate Garrish, before summer break starts. Her fellow students and workers are going about their end of the year business, and Kate's brief run ins with them are as awkward as any random hallway encounter. Except that Kate isn't a fan of people or talking. After a few encounters and internal fighting, Kate runs back to her dorm, locks herself in her room at the story's end, grabs a rifle. Then all hell breaks loose.
