Four sexually frustrated chaperones

Three hapless kids caught vaping in the bathrooms

Two heated kisses

One ghost ship on the San Francisco Bay turns this joyous celebration into one helluva creepy night...

Meet siblings Ramona and Ruben, veteran teachers at Baymont High School. They've been chaperoning proms for years, but tonight they'll need all of their faculties to protect their students from beings who may or may not have evil intentions. Oh, and manage to keep their family's secret while attempting to get closer to their respective love interests. No problem, right?
