Cry of the Penguins (1971)

A young london biologist spends most of his time pursuing girls rather than pursuing science. When the opportunity to go to the Antarctic to study a colony of penguins presents itself, he agrees to go, not so much for the benefit of science, but rather to impress the girl he has recently been chasing. The longer he stays in the Antarctic, however, the more he becomes truly interested in the penguins fight for survival. When the time to go home finally arrives, he is a changed man with a totally new outlook on life.
