A family descends into a vortex of denial and paranoia after the death of the oldest son. Though labeled a suicide, the bizarre circumstances lead the mother, Helen, to believe there are darker forces at work. Black paint was thrown over everything reflective in the son's decrepit Victorian house, an explosive trap set in his bedroom and a woman from his past haunts the cemetery where he lies buried. But when Helen's investigation threatens to ruin the life of her teenage daughter, Kate, and possibly her own sanity, she realizes there is but one escape from this nightmare world - the very route attempted by her dead son. Finale captures mystery, horror and suspense in the colorful visual style of the 1970's Italian gialli.
