In February 2019, Andres, a 52-year-old German pianist living in Seoul, plays Beethoven’s Sonata No. 14 when the second summit between the US president and North Korea’s leader ends without any deal. It reminds him of the moment when the Wall abruptly fell down 30 years ago in Berlin. 1989 Berlin, Seoul 2019 is about three East and West Germans who were faced with the collapse of the Wall as teenagers and have lived in South Korea for over 15 years. Now they're facing an atmosphere that may lead to reunification in South Korea. As Koreanized Germans who experienced unification and know Korean society as well, Andres, Mark, and Sonya start to reveal its bittersweet consequences and share controversial futures if the two Koreas were to become one. This November, Andres and Mark will return to Germany to join a concert for peace and to meet a pen-pal who lived on the other side of the Berlin Wall. Sonya starts guiding DMZ tours and preparing classes to talk to youngsters about what our future holds. What will happen to us if we're made one?​
