Dancing great Bill 'Williamson' sees his face on the cover of Theatre World magazine and reminisces: just back from World War I, he meets lovely singer Selina Rogers at a soldiers' ball and promises to come back to her when he 'gets to be somebody.' Years go by, and Bill and Selina's rising careers intersect only briefly, since Selina is unwilling to 'settle down.' Will she ever change her mind? Concludes with a big all-star show hosted by Cab Calloway.
