A young Chicago advertising executive believes a woman he sees in a café is his long-lost love. His belief leads to obsession, as he puts his life on hold in order to trail her.

Randal 'Randy' Ackers loses his family savings and the company's reserve funds in an 'easy profit scheme' and commits suicide. His widow Dianne hopes to build a new life in California but gets stuck with car trouble in Texas. To pay for the repairs, she becomes waitress Dee Dee in a diner. There the swindler, who apparently doesn't recognize Diane, recruits 'Dee Dee' as investment sales pitch assistant. Friendly local sheriff Nando, who has a crush on her, promises to help catch the trickster under his new name, unofficially as he has no cause for legal action. But more is not what is seems.
