Spring has sprung, but a snowstorm hits Nebraska, forcing the Drs. Erin and Ben Schroeder to contend with unpredictable weather. Despite the snow, springtime for the docs means helping to bring new life into the world, whether it's doing a pregnancy check on a herd of 200 cattle; artificially inseminating a German shorthair dog; or wrangling a potentially pregnant pot-bellied pig.

Dr. Ben Schroeder and son Charlie are surprised when a young family brings in an orphaned raccoon they found in their shed, while Dr. Erin Schroeder helps a woman subdue a trapped cat with a serious dental issue. Ben and his younger son Chase also encounter a newborn calf with a hernia the size of a melon and perform surgery, while Erin tries to uncover why a terrier is suddenly experiencing violent seizures. The Schroeders also get a visit from a family of llamas, one of which is expecting, and the whole clan ventures into a massive thunderstorm to aid a downed dairy cow.
