Lenny is a hopelessly out-of-touch amateur sleuth obsessed with anything and everything mysterious. When his parents leave town for the weekend, his older brother Steven takes their absence to his advantage by throwing a huge high school “Halloweekend Rager”. As the party booms below, Lenny finds what he believes to be a murdered partygoer covered in her own blood. He can’t tell Steven. He can’t go to his parents. He takes matters into his own hands, embarking on a personal investigation to find the costumed killer. In this sinister Halloween Who-Dunnit, we follow Lenny on a misguided mystery full of twists.
