Paul and Eddie are veteran paranormal monster hunters and a new recruit named Vanoss desperately tries to join their team. They get alerted by an old lady that her house was taken over by ghosts who are partying to loud music. Paul and Eddie leave Vanoss behind, since he is inexperienced. They, aided by Pad - an extremely intelligent supercomputer designed to detect paranormal activity - and Orb - a football-sized magical sphere containing a powerful and immortal female being inside - , infiltrate the party and realize that the ghosts cannot leave, because they are controlled by DJ, a demon called a Canaanite Lord of the Covenant. The two find out how demon is controlling the ghosts: through the music. As they are cornered by the demon, Vanoss arrives to the rescue and changes the loud techno music to Paul's romantic tape, which destroys the demon and releases the ghosts. (thetvdb.com)
