Egon on the Rampage

A news crew attempting to expose the Ghostbusters as frauds cause problems for the guys at the firehouse. Egon lets them view a test of an experimental project, a dimension-o-meter, a device that will eliminate the need for the containment unit storage. After a demonstration, the news crew cause the machine to go haywire. In the process, Egon's soul is switched with a demon turning him into a giant purple monster. Ray and Winston attempt to catch up to the rampaging monster while Peter enters another dimension in an attempt to find Egon's soul before it's too late!
