The plot concerns a family pursued by vegetarian goblins who seek to transform them into plants so that they can eat them. The English-language script was written by Fragasso and his wife Rosella Drudi, neither of whom actually spoke fluent English at the time. Despite filming the movie in Utah, and casting the movie entirely with American actors (many of whom had no prior acting experience and had responded to the casting call hoping to be extras), Fragasso also employed an exclusively Italian crew, who likewise spoke no English. The resultant communication breakdown, coupled with the cast's lack of experience and Fragasso's insistence that his script be performed verbatim, has led to the movie being considered one of the worst movies ever made.
