ABC NEWS' "NIGHTLINE" LAUNCHES "PRIMETIME NIGHTLINE" SUMMER SERIES, 13 ONE-HOUR SPECIALS STARTING WEDNESDAY, JUNE 29

ABC News' 13-week primetime summer series, "Primetime Nightline," premieres WEDNESDAY, JUNE 29, with a five-part investigation into the realm of the extra-sensory, the spiritual and the experiences many call "beyond belief."

Note: This series was originally scheduled to premiere on June 22.

"Sometimes the most interesting trips are the ones that take you places you never thought you'd go. These are mysteries in the most profound sense," says "Nightline" executive producer Jeanmarie Condon. "Stories that defy proof and perception are the ultimate adventure - and perfect for summer - to kick off our 13 specials."

The five installments of "Beyond Belief" begin airing Wednesday, June 29 (10:00-11:00 p.m., ET) and continue on the four subsequent Wednesdays (through July 27):

Wednesday, June 29: Juju Chang investigates "Twintuition," the special connection between twins that allows some siblings to share a language, know what the other is thinking, or share physical sensations across distances. If twins can communicate on a level that defies spacial and time constraints, what does that mean for the rest of us?

Wednesday, July 6: "Nightline" co-anchor Bill Weir journeys from Nazareth and Rwanda to Spain, Bosnia and across the U.S. to explore "The Miracle Mysteries." These destinations have become pilgrimage sites for people who believe profoundly that the Virgin Mary has appeared to and communicated with ordinary people.

Wednesday, July 13: "Nightline" co-anchor Terry Moran takes a closer look at the "Battle with the Devil," a resurgent belief that satanic will or demon possession causes acts of evil. Can a real-life killer get away with the "demon defense" for murder?

Wednesday, July 20: Juju Chang and others unravel the power of the 21st century psychic. "Psychic Power" features a medium to the stars, psychic addicts who can't make a decision without consulting a clairvoyant, and people who believe their pets are psychic.

Wednesday, July 27: Bob Woodruff unlocks the mysteries of what he remembers in the terrible minutes after his vehicle hit an improvised explosive device and he saw his body floating below in a kind of whiteness. He speaks with others who report the same type of out-of-body experience and with theologians, preachers, neurologists, psychologists and anthropologists for "The Other Side."

"Nightline's" summer series builds on the success of a four-part exploration of the mystery and the science of the brain that aired in primetime last year. ABC News' "Nightline" is anchored by Cynthia McFadden, Terry Moran and Bill Weir. John Donvan and Juju Chang are correspondents. Jeanmarie Condon is the Executive Producer. The program airs weeknights at 11:35 p.m., ET on ABC.
