For the first time, scientists, using the latest DNA technology, are able to track the salmon from the rivers, through the estuaries and into the North Atlantic Ocean and back again, in hopes of finding an answer before it is too late.

Producer Deirdre Brennan will introduce the film, followed by a question-and-answer session with Jonathan Carr of the Atlantic Salmon Federation.
