A hungry predator encroaches deeper onto North Star Ranch forcing Bird and Gabe to take stronger action. Bam must play nice with his siblings in an effort to finally break ground on his homestead. Gabe has an incredible surprise for the Wolf Pack.

When an ostrich lays its first egg, the Brown siblings rush to figure out how to incubate it. Bear gets a special visit from a girl on North Star Ranch as the family prepares for a surprise celebration for Billy and Ami's 40th wedding anniversary.
