Michaela Strachan meets Wendi, a two-year-old orphaned elephant that has become leader of the herd of baby elephants at the Nairobi nursery. Jonathan Scott tries to win over 10-year-old Emily, matriarch of the older orphans who are on their way back to a life in the wilds of Tsavo National Park. Meanwhile, a rescue team heads to Samburu National Reserve to try to save a starving orphan rejected by the rest of the herd.

In Nairobi, the team check on newly rescued baby elephant Naserian's condition. Michaela Strachan follows preparations to move Wendi and five older babies to a new release site.

Wendi and her charges struggle to settle at their release site in Ithumba. Four of the older female orphans are separated from Emily's herd and sent to Ithumba to help them acclimatise to their new surroundings. But the plan goes badly wrong. Meanwhile, back in Nairobi the remaining baby elephants must cope with losing Wendi.
