Reeling from the deaths of his wife and mother, 25-year-old Theodore Roosevelt decides his place isn't among the social elite of New York, but on America's frontier. He abandons his political aspirations and heads for the lawless Dakota Badlands, where he plans to become a cattle rancher. While still experiencing overwhelming grief and wrestling with debilitating asthma, Roosevelt draws on the guidance of his lumberjack mentor from Maine, Bill Sewall, and his cowboy partner, William Merrifield. As they work to establish the sprawling Elkhorn Ranch, it's Roosevelt's youth and physical frailty that make them an easy target for local gunslingers, land speculators, and cattle rustlers. In his first few months in the West, Roosevelt must disarm a barroom bully, face down hired guns, track down horse thieves, and kill a grizzly bear. Along the way, he forms lifelong friendships and begins to remake himself into the man who will forever be identified as The Cowboy President.

"America's Funniest Home Videos" was inspired by a series of successful TV specials, where home viewers were invited to send in videotapes of their "funniest" moments. In "AFHV," host Saget provided commentary to the home videos which often showed wedding and sports bloopers, children and pets either being themselves or getting into trouble, furniture or other objects giving way (usually contributing to someone's fall) and "comical" reactions to getting inadvertently hit (usually in the groin). Sometimes, certain videos were grouped into themes, such as Christmas or a summer vacation, or had sentimental value to them, such as a marriage proposal; other times, videos were set to classic rock tunes. The top three videos of the week as selected by the producers were eligible for each week's $10,000 top prize; the audience would electronically vote for their one favorite video. Weekly winners got to compete in a later special for a $100,000 top prize.
