Research chemist Barnaby Fulton works on a fountain of youth pill for a chemical company. One of the labs chimps gets loose in the laboratory and mixes chemicals, but then pours the mix into the water cooler. When trying one of his own samples, washed down with water from the cooler, Fulton begins to act just like a twenty-year-old and believes his potion is working. Soon his wife and boss are also behaving like children.

Tuercas
Devout Christians Töre and Märeta send their only daughter, the virginal Karin, and their foster daughter, the unrepentant Ingeri, to deliver candles to a distant church. On their way through the woods, the girls encounter a group of savage goat herders who brutally rape and murder Karin as Ingeri remains hidden. When the killers unwittingly seek refuge in the farmhouse of Töre and Märeta, Töre plots a fitting revenge.
