Among this, the Mikami GS Company, led by Reiko Mikami and her two assistants, the teenage boy Tadao Yokoshima and the ghost girl Okinu, is said to be the best.Parapsychologists Peter Venkman, Raymond Stantz, and Egon Spengler are called to the New York Public Library to investigate recent paranormal activity.
They develop high-tech equipment capable of capturing ghosts and open their business in a disused, run-down firehouse.
Egon warns them never to cross the energy streams of their proton pack weapons, as this could cause a catastrophic explosion.
They capture their first ghost, Slimer, at a hotel and deposit it in a specially built containment unit in the firehouse basement.
As paranormal activity increases in New York City, they hire a fourth member, Winston Zeddemore, to cope with demand.
Sinópsis: La historia comienza cuando Mikami y Yokoshima estn realizando un trabajo: el de destruir un fantasma que data de muchos aos de historia.
