From the Tammi/Elina Ahlbäck Agency Rights Guide:
Worms is an intensely emotional tale of the long shadows cast by the past and atonement for irreversible deeds. It is also a story about modern day people clinging to their blind faith in their own free agency as they are faced with the forgotten secrets of the past. On a barren island lurks the mysterious legacy of a shipwreck, marked by nine stone graves and a small, dilapidated chapel. These ghostly memorials conceal an ancient tragedy and an ideology in which a sinner is of no more worth than a worm crawling in the dirt. And on the island, that legacy appears to live on.
