Watch HDToday. Welcome to Lisbon: there are mermaids by the Tagus and birds flying over the old city; there are mad scientists and singing fish; lost tourist guides and lost tourists; fado and sad guitars. What a weird city you may think - but no. Lisbon is about being different, sarcastic, welcoming to foreigners even in an economic crisis. Different directors became fascinated by our strangeness. We became fascinated by these directors. The city is never the same in these four episodes, here in Lisbon.
