Little Black Box (2016)

Many women keep at least a list documenting the names of all their sexual exploits. Cece, on the other hand, keeps a box full of keepsakes to remember all her partners. Toward the end of a college reunion party at her apartment, two of the men for whom she has mementos stay to help clean up the party's aftermath. Both are unaware of the other's history with Cece, both believe they took her virginity, and what seemed like a simple collection of mementos creates pandemonium between old hook ups.
