In the follow-up to 'I Love Lucy,' Lucille Ball plays widow Lucy Carmichael, a mother of two children who shares a home with divorced friend Vivian Bagley (Vivian Vance of 'I Love Lucy' fame). Carmichael is always scheming—dragging Vivian along with her—and grappling with comic complications related to life on her own and serving as secretary to the grumpy and demanding Mr. Mooney.
