In search of the Nile

When life in the Habar tribe gets more and more difficult as the plains dry up, the tribe leader decides to marry his daughter to the son of the nomadic tribe leader.
The two tribes hate each other, there is a rumor of a river that never dries up in the north, but the elders are not willing to leave the land of their ancestors. The children of the tribe have to put their differences aside and make a very difficult decision when the small stream that fed the village finally runs dry.
They abandon all adults and old people, going on a journey of no return in search of the promised river that never dries up.
Do you think they made this prehistoric journey safe?
And the two princes? Will you fall in love in the end or fight for the power of your small tribe of 15 children?
