The story revolves around Carolien (Margôt Ros) who, during her move back to Eindhoven on Christmas Eve, ends up in an empty and dark house. By coincidence she runs into a special invention of her father. This turns out to be the very first smart speaker in the world, but from the 1970s. Unconsciously Margôt activates this smart speaker with the words 'Hey Endje'. This awakens this prototype and unconsciously sets in motion a series of events that make her Christmas Eve 2020 an unforgettable evening. Because: what is Christmas without music, good food or nice people around you? And will the mistletoe of neighbour Fred (Theo Maassen) bring love? In addition to well-known Eindhoven headlines, there is also room for various Eindhoven entrepreneurs.
