For around three weeks, producer Lydia Baines trailed a family of smooth-coated otters in Singapore. Or, more accurately, she and her team raced after them.

“Otters are not slow animals. They are absolutely crazy fast once they start going. So we were running around Singapore in trainers with our gear in a trolley and listening down drain covers trying to find them again after we lost them,” Bainestells The Straits Times in a Zoom interview.
