Izlet (2011)

Ziva, Andrej and Gregor are best friends since high school. Gregor is a soldier who is about to embark on a mission to Afghanistan and Ziva is going to study abroad. Andrej is their gay friend who hates everything, himself included. They decide to go to a road trip to the seaside like they did when they were in high school. When they arrive, they get drunk and Ziva and Gregor kiss each other, what brings tension to their relationship, while Andrej doesn't know anything and just makes fun of everything, mostly of Gregor and his army ideals. The conflict erupts when Ziva, in a fit of rage, destroys their tent and tells a secret that enrages Andrej. Only then the true problem is revealed - Ziva is not going to study abroad, she was lying because she didn't want to pity her.
