More than 15,000 immigrants from Southeast Asia have settled in São Teotónio in recent years, until then a quiet Alentejo parish of just 6,000 inhabitants. And they continue to arrive, day after day, to work on the harvest of red fruits in greenhouses that proliferate within a natural park. Greenhouse Effect is a documentary series about the consequences of this phenomenon. And it is, at the same time, a look at the big issues of the contemporary world, such as globalization, migrations, political conflicts, water scarcity and a future that seems more uncertain than ever.—SIC TV
