Something is going on with the people next door

Two completely different couples live in the same building complex. Thanasis runs a mobile phone shop. Behind it, he has set up a business selling illegal CDs. Gogo's wife aspires to become a popular singer. Manos is a painter without any recognized talent and is married to Eleni, an associate professor of sociology. However, something is wrong with these two couples. The two couples belong to completely different worlds, which constantly clash with comical results... Thanasis with Gogo or perhaps Gogo with Manos? Manos with Eleni or Eleni with Thanasis?
