It is a peaceful life the lobsters live there at the shore of Monhegan, mostly only interrupted by looking for the next tasty clam. A perfect idyll, if it wasn’t for the lobster traps, which, despite all the warnings, keep claiming victims. When they catch the uncle of young Daniel Lobster, he is determined to fight back. After being caught himself, he builds up a resistance group together with the other crustaceans, and starts to make life very difficult indeed for the big land creatures.
