Ernest suffers from catalepsy (where the sufferer appears dead) so when he goes off alone, his wife is right to worry.
He suffers an attack and inadvertantly becomes separated from his MedicAlert bracelet and the letter he keeps on his person to advise anyone who might find him.
Fortunately his jacket comes into the possession of a married couple of which the wife is worried by the letter.
Meanwhile Ernest, presumed dead, is taken to the morgue to be embalmed....
