The Penthouse begins with the inclusion of two foreign guests in a large and warm family. Ates and Yasemin, who joined this family, living with solidarity and holding onto each other with a tiny "lie", will first collide with love under this roof, then be tested with their lies, but they will see friendship, sharing and love over time. The Penthouse is actually the story of those who are new to life, those who carry the world on their backs, who knit their nest knot by knot. But above all, it is a love story. It is the story of Ates, Aysen, Demir and Yasemin, whose characters are opposite to each other and come from different social classes and cultures, to resist their love at the expense of their families.
