Peck returns with law-enforcement and city workers to have the Ghostbusters arrested and their containment unit deactivated, causing an explosion that releases the captured ghosts. Louis/Vinz escapes in the confusion and makes his way to the apartment building to join Dana/Zuul. In jail, Ray and Egon reveal Dana's building was designed by Ivo Shandor, leader of a Gozer-worshipping cult, to function as an antenna for attracting and concentrating spiritual energy to summon Gozer and bring about the end of the world. Faced with paranormal chaos in the city, the Ghostbusters convince the mayor to release them.
