Step by Step is a classic 1990s sitcom that follows the chaotic lives of Frank Lambert, a carefree contractor, and Carol Foster, a structured beautician. After meeting on vacation and impulsively getting married, they return home to Port Washington, Wisconsin, to merge their two disparate families under one roof. The premise centers on the clash between Frank's three rowdy children—J.T., Al, and Brendan—and Carol's three perfectionist children—Dana, Karen, and Mark. As the series progresses, the blended family navigates the typical trials of adolescence, sibling rivalry, and the adjustment to their new living situation. The show is anchored by the comedic tension between the two parents' opposing parenting styles and the constant interference of Frank's nephew, Cody Lambert, who lives in a van parked in their driveway. Over its seven-season run, the series explores themes of compromise, acceptance, and the evolving dynamics of a modern blended family.
