Dropping Like Flies

"Dropping Like Flies" is pretty much a love letter to films such as "The Final" (2010), "Unfriended" (2014), and Agatha Christie's "And Then There Were None," and "The Mousetrap."
While a group of teens and young adults are staying on Belmonte Island for the weekend, a tape is discovered that accuses them all of killing a girl. As the group tries to leave, it becomes clear that they are stranded and have nowhere to go. As the body count rises, and accusations fly, the remaining few struggle to understand how they are involved in the girl's death, causing everyone to ask the same question: Is the girl really dead, or is she alive and seeking revenge?
