John lives in New York with his wife of several years.  Only one other person knows of his hideous deed, and he's blackmailing John for all he's worth.  Hiding his past from her gets more difficult with each passing day. 

Elizabeth lives in Honolulu.  She meets the man of her dreams but then inadvertently gets involved in a smuggling racket.

When they finally meet, neither one is spilling the beans, except for the one person who knows about both.
