In central Botswana elephants are known to roam far and wide; their movements dictated by the rains and food sources. In times of desperation and drought, they fall back on one plan – an impromptu migration into the Okavango Delta. This film documents the desperate struggle of a 34-strong elephant herd as they set out from the parched Kalahari Desert to reach this green sanctuary – a journey of over 100 miles.
