Dr. Gillespie's (Lionel Barrymore) assistant, Dr. Red Adams (Van Johnson), is still fending off the romantic advances of beautiful blond socialite and social worker Ruth Edley (Marilyn Maxwell), who finally succeeds in winning Red's heart.

[3] There are some scenes in the singer's night club that draw inspiration from the country's immersion in the Second World War.

(Allmovie.com's synopsis of the movie has Red romantically involved with ailing socialite Cynthia Grace (Lucille Bremer), who supposedly suffers from a life-threatening blood clot,[4] but this is the plot for Dark Delusion.)

The draft script included a plotline involving twin sisters, one of whom is pregnant, that Dr. Adams and Dr. Gillespie believe are the same person.

To avoid any financial impact from a rejection of the finished film, MGM eliminated the twins plotline in a script rewrite.
