Show Me Your Friend (2006)

Agamemnon Anafentos and Achilles Strakkas are two 55-year-olds, former close friends and now enemies, after Agamemnon, under pressure from his parents, married Achilles' daughter, Despoina. They are both owners of two large construction companies, which compete in general but especially for a large public contract, which they fight tooth and nail to win. However, fate, which usually acts independently of people's will, will involve them in major and comical adventures, starring not only themselves but also their children: Anna and Thanasis, Achilles' children, and Themis and Andria, Agamemnon's children. The two daughters feel deceived by a young, handsome actor, who is dating both of them at the same time, and in their attempt to take revenge on him, they will get involved in new romantic adventures, with their two sons as co-stars and with consequences that could bring their fathers to the brink of a stroke.
