This Island Earth

When atomic scientist Dr Meacham (Rex Reason) is chosen to take part in a top-secret research experiment in a remote lab, he quickly discovers that he is really involved in an evil scheme by alien Metalunans to take over Earth. After he and the gorgeous Dr Adams (Faith Domergue) make their escape shortly before the lab explodes, they are whisked away in a flying saucer to Metaluna, where they are blamed for the destruction. Will interstellar negotiation save the day or will the scientists be forced to take part in a treacherous battle to the death?
