He Walked Through the Fields(Hu Halach B'Sadot)

Uri, the first son of a "kibbutz", comes home from 2 years of studying. He finds his father has joined the British army, and his mother is with another man. He meets Mika - a new immigrant from Poland - and quickly falls in love with her. He is then torn between his commitment to his home family and girl, and between the "Palmakh".
