In "Ghost Adventures," Zak Bagans and his team of paranormal investigators have visited hundreds of haunted locations both in America and abroad, interviewing locals about alleged hauntings before going face to face with supernatural entities. Along the way, Zak and company have provided answers and help for couples, families and individuals suffering the vengeance of spirits. "Aftershocks" follows up by having the series' most memorable characters recount how things were before Zak's "lockdown" investigation and how their lives have changed since. Are questions still left unanswered? In some cases, paranormal teams that have investigated specific locations after the "Ghost Adventures" team bring their own evidence and insight to the table.
