Tonight and Every Night is a 1945 American musical film directed by Victor Saville and starring Rita Hayworth, Lee Bowman and Janet Blair.

[1] The film portrays wartime romance and tragedy in a London musical show, loosely modelled on the Windmill Theatre in Soho, that determined not to miss a single performance during the Blitz.

Stage manager Sam Royce recalls the halcyon days at the beginning of the war: Theatrical impresario May "Tolly" Tolliver is rehearsing her performers when dancer Tommy Lawson comes to audition.

When German planes discharge their bombs over the theater, the audience and performers take refuge in the basement, and there Paul meets Ros and invites her to dinner.

Ros begins to date him, but when he tricks her into coming to his apartment by promising to introduce her to a non-existent soldier from her home town of St. Louis, she feels betrayed and refuses to talk to him.

When Ros receives a note from Paul's father, Reverend Gerald Lundy, asking to meet her after the show that night, she assumes that he has sent him as an emissary to terminate their relationship.
