Mars is a relationship romance about the loves, friendships, hopes and fears we collect throughout our lives on Earth and then take to another planet. But even there, we are drawn back to Earth, to Mars. Gravity just works everywhere, as everyone knows, because the time when the red planet was in vogue is long gone. The Martian Science Station is maintained in emergency mode by an obsolete robot, Bot, once left to its fate on Mars. He's survived five major dust storms, read only Indian comics and been struck by lightning several times. He doesn't want to be alone anymore. But instead of spare parts, a Czech expedition is coming. The tourists come for different reasons, some want to get married on Mars, others are convinced they're on an adventure reality show. The members of the expedition have such different personalities that things soon start to sour between them, and Bot the robot longs for a time when flights to Mars have long gone out of fashion.
