A horror movie shot in Camden, Rockport, and Islesboro will be shown this weekend at the Emerge Film Festival in Lewiston/Auburn. 

The story was written by best-selling author Tess Gerritsen, who's now making the jump to the big screen with this low-budget horror film. 'Island Zero' tells the tale of an island community that suddenly finds itself cut off from the mainland. Ferry service isn't running and radio communication isn't working. When people start disappearing, the residents realize that someone (or something) is hunting them.

Gerritsen, who is a retired physician, has written more than two dozen suspense and medical thrillers. 'Island Zero' is a family project with Tess writing the screenplay and her son, photographer Josh Gerritsen, directing. It debuted earlier this month in Boston and will make its Maine premiere this weekend. And it looks really good!

Emerge is a 3-day festival that brings Maine-made, national, and international films to Lewiston/Auburn in April. This year's festival is scheduled for April 27 to the 29th and includes screenings, after-parties, and discussions. 'Island Zero' will be shown Saturday afternoon at 4:00.
