A team of scientists arrive on a remote island to study the effect of nuclear weapon tests on local fauna. However, a scientist who was already supposed to be there has gone missing. Mysterious noises are heard of night and people start to die. The voices of some of those who have died, including the original scientist are heard at night...
To the horror of Dale (Richard Garland) and Martha (Pamela Duncan) the voices are from gigantic killer crabs! The radiation mutated crabs have eaten humans and absorbed their memories, and can even speak like them. The crabs are also impervious to anything fired at them...
Monster movies from this period are usually not the best of films but this one isn't that bad. It has some genuine suspense and builds the terror well. The monster crabs do not appear until well in the film, they arn't really worth the wait but you'll see a lot worse.
