A claustrophobic sense of doom pervades the Summer of 1970, the final present-day storyline on Dark Shadows. In it, Barnabas Collins and Dr. Julia Hoffman try to unravel the mystery behind the insidious and increasingly malignant hauntings at the great house in an effort to prevent the destruction of Collinwood and its inhabitants. Meanwhile, they must also deal with a mysterious new vampire who prowls the estate. Professor and writer David M. Wingrove and writer Stephen R. Shutt visit the Terror at Collinwood podcast to dissect and explore this oft-ignored and/or scorned storyline, examining its various literary inspirations along the way. Often seen as DS’ attempt to recapture the success of the 'Turn of the Screw'-inspired “ghosts of Quentin and Beth” storyline, Summer of 1970 pulls inspiration from several classic sources, including tales by Oliver Onions and M.R. James, with a nod to Sheridan Le Fanu.

The 1970 Parallel Time storyline introduced Dark Shadows viewers to a strange and fascinating parallel universe inhabited by alternate versions of familiar characters who, in this mirror timeband, made different choices in their lives. Visiting to discuss this unique story arc are fellow DS podcasters Cara Tillitz and Christen Pierce of the Between the Shadows podcast and Jule Saynes of the Resident of Collinwood YouTube podcast channel. In addition to discussing the plotlines and characters of 1970 Parallel Time, and their inspirations, Cara, Christen, and Jule also talk about their introductions to Dark Shadows and why they launched their own DS-focused podcasts.
