A charming TV show. The intros and outros of John Newland make it all the better.

Echo is a well crafted episode of the One Step Beyond series, and it features an intense central performance from Ross Martin as a man suffering from pangs of guilt over recently having murdered his wife, then being acquitted of the crime, now haunted by his conscience.

Or is he?

Maybe it's his unconscious mind that's tormenting him. Could it be that he's innocent after all? He appears to be suffering from delusions, premonitions, strange sounds; of thunder and baying dogs. Does this suggest guilt or perhaps merely a man on the edge of madness whose imagination is playing tricks with him?

Whatever truth of the matter, this man appears unlikely to recover from what's tormenting him, as he appears to be bringing upon himself a fate, a punishment he believes he deserves. The ending of the story consists of a neat summing up of these issues, and yet one cannot but wonder if this man is delusional, suffering from hallucinations, not truly guilty at all..
