The Ghoul Girls

After a gas leak in their apartment, four girls attending Hillstone University die tragically in their sleep. They realize quickly that they are stuck in the apartment as ghosts for the rest of eternity. With new roommates moving into their apartment the following year, the girls come up with a plan to have some fun and scare them. But when the same problem faces the new girls, the ghosts must figure out how to stop them from reaching the same fate they did.
