Peter Venkman, Ray Stantz, and Egon Spengler all work at the same university, where they fiddle with many unethical experiments on their students and mess with the paranormal. As they are kicked out of the university, they go into business for themselves, hunting and catching ghosts.

When a downtown skyscraper becomes the focal point of spirit activity linked to the ancient god Gozer, however, the problem may be more than the team can handle. Remember! Don’t cross the streams!
