We’ll follow two otter families and encounter macaques, pythons and stingrays battling to survive and learning to flourish in the waterways of Singapore. The city's canals, rivers and reservoirs criss-cross a thriving metropolis, vitally connecting the people and water wildlife. The development of complex water networks across the city has led these animals to thrive in unexpected and remarkable ways. Many of their behaviours have never been witnessed before, and showcase wildlife's incredible adaptability to city life. Narrated by wildlife TV expert Patrick Aryee.
