Portugal's capital city of Lisbon lies on the western edge of the Eurasian continent. A port town, it was the starting point for Francis Xavier and many other great explorers during the Age of Discovery beginning in the 15th century. Characterized by many steep slopes that have earned it the nickname "City of Seven Hills", Lisbon is also famous for its social tolerance and the warm welcome it extends to immigrants from all over the world. On this walk, viewers meet a variety of friendly people of all ages, including college students celebrating the entry of new students to their schools; gentlemen enjoying an afternoon round of card playing; senior citizens searching for love at a social dance club; and a young singer carrying on the traditions of her native land by performing fado songs.
