Mild-mannered Brad Whitaker is a smooth-talking radio executive who strives to be the best possible stepfather to his wife Sara's two children, Megan and Dylan. Brad pours his heart and soul into winning the kids over and being the perfect parental figure. Despite his earnest efforts, he constantly finds himself in comically unfortunate situations that hinder the bond he's trying to create. While Sara sees Brad's genuine attempts and supports him, the children are slower to come around, keeping him at arm's length in their affection. Brad's world is turned upside down with the unexpected arrival of Sara's ex-husband, Dusty Mayron, a muscular, charismatic, and freewheeling bad boy.

Dusty’s return shakes the already precarious family dynamic as he sets out to reclaim his place in the kids' lives and Sara's affections. With a natural coolness and a propensity for excitement, Dusty effortlessly starts to undo all of Brad's hard work, making him seem dull and overly safe in comparison. As the ultimate alpha male, he makes Brad look insignificant, causing a fierce rivalry to ensue. The competitive back-and-forth escalates as both Brad and Dusty go to great lengths to outdo each other and win the family's favor, resulting in a series of comedic and outrageous oneupmanship that puts Brad's determination and Dusty's slickness to the test.
