The little elephant orphans are back! It's time to catch up on some old friends and meet some new ones as they face some of the biggest challenges of their short lives. For a baby elephant, family life is everything and losing your mother is the worst possible start in life. Elephant Diaries returns with another emotional roller-coaster of year in the lives of a unique group of orphaned baby elephants rescued by The David Sheldrick Wildlife Trust in Kenya. Here they are nurtured by dedicated keepers who become their "surrogate mothers". But will they ever be able to recover from the loss of their own mothers and face up to the challenges of taking their first steps back into the wild? Tonight, Michaela Strachan is in Nairobi where she catches up with Lualeni, the grief-stricken little orphan who watched her mother die. One year on, will she have come to terms with her devastating loss? Jonathan Scott is back in Tsavo where Emily, the old matriarch of the orphan herd who is now living wild, has a surprise for him. Jonathan is also reunited with Wendi, once the leader of the baby elephant orphans, who is now a 4 year-old with an identity crisis. And a full scale emergency unfolds as a tiny baby elephant is left for dead in the wilds of Tsavo National Park.
