At the gateway of the world's best airport - The Accident and Emergency Service face a fiery explosion and a penniless backpacker needs to find a way out of Singapore.
We follow the trials and tribulations of Changi's customer service teams as they handle passenger problems. We join Cisco security on patrol, and a new batch of Singapore Airlines staff are initiated.
At Changi Airport, over 55 million passengers pass through its terminals every year. But it's not just humans. We follow staff as they take on migrations of pilgrims, passengers and wildlife.
