Wednesday, 8.30pm, SBS One Ah, just when you’re expecting a wonderful documentary about an all-night supermarket in Venice, this turns out to be one of those ambulance-chasing series, with access to the real operations of emergency services. Apparently up to 50,000 tourists pile into Venice each day for the carnivals, culture and canals. But, according to the narrator, what the tourists don’t see is how the city works. ‘‘ This is Venice from the inside, as round-theclock emergency teams fight to keep the city built on water safe and working,’’ he says. Naturally there is a lot of the usual medical and fire dramas you find in such programs. Yes, even houses built on water can catch fire. But what makes this really worthwhile is the beauty of the city seen from all angles and at all hours of the day and night. Did you know that as tourist numbers increase resident numbers plummet? There are now fewer than 60,000 people who live in Venice year-round. In winter the city is handed back to them and this brief window of opportunity is used to repair and rehabilitate the sagging city.
