The family tackle their second lockdown during one of the worst winters they have ever faced, and have to juggle work on the farm with the childrens' homeschooling. Later, when an arctic blizzard batters the farm, Amanda and Clive face a desperate search to find their lost sheep, and Clemmie and the rest of the children have to give newborn Misty and the rest of their calves constant care in the freezing cold.

Amanda attempts to forge a new partnership with Clive's headstrong young sheepdog and tragedy befalls the farm when 40-year-old Shetland pony Little Joe passes away. When ash dieback strikes, the family is forced to call in local fellow farmer Morris to help fell a decades-old tree and stop it collapsing onto a traditional stone barn. Using wood from the ancient tree, the children craft a headstone for Little Joe and help dad Clive lay the last of the earth on the pony's grave.

The children are off school for the Easter holidays, and the family prepare for their busiest time of the year as lambing season begins. The lambing hospital shed has already began to fill up, so while nine-year-old Sid takes it upon himself to bed up a private room for a mother and her newborns, five-year-old Clemmie and seven-year-old Annas help Amanda deliver a pair of twins who are stuck.

Clive is concerned the freezing spring weather is set to worsen, with over 500 lambs still on the way, and the family must travel across hundreds of acres twice a day to top up the food of their free-roaming sheep. When a ewe struggles to feed both its lambs, Amanda teaches Nancy how to borrow milk from another mother and use the farmhouse's warming oven to resuscitate a weak newborn.

June arrives and Reuben has an entrepreneurial plan to start a digging business and shows Sidney how to flip a used trials bike, while Clive has a surprise for 12-year-old Edith - she's to become the proud new owner of a sheepdog puppy. While her siblings are at school, Amanda and Clive are encouraging Nancy's writing skills, tasking her to record the spring lambs that they are vaccinating and, to further Nancy's pre-school lessons, 20-year-old Raven encourages her to paint a name sign for Tony the pony's stable.

It's the summer holidays, and 17-year-old Reuben has taken some time off to help his parents with their biggest summer job - hay cutting. Meanwhile, Amanda and Clive enlist the help of Miles and Edith to shear their thousand-strong flock, and later Amanda takes the children for a well-earned swim in one of the family's favourite swimming holes, where she reflects on their successful summer.
