Warsaw never sleeps. Particularly in Powisle, where the bars sound with laughter and the river reflects the city lights like blurred neon streaks. Amidst the crowd, on this June evening, four strangers - Lena, Artur, Jagoda and Igor - meet for the first time by chance at the "Próg" club. Each of them found themselves there for a different reason: Lena was running away from her own thoughts, Artur was celebrating a session at the polytechnic, Jagoda came with a new acquaintance, and Igor.... Igor was constantly looking for something, although he didn't know what himself. For a while the atmosphere was ordinary. Someone brought shottos for winning at darts, music pulsed underfoot, lights flashed on walls lined with red brick. The smell of citrus and summer night was in the air. Suddenly, the electricity throughout the building went out. Silence reigned, broken only by the murmurs of confused visitors. Lena felt her skin begin to tingle slightly - as if someone was touching her thoughts. Artur noticed that tiny sparks had circled around his hand, even though he had not touched any wire. Instead of panicking, Berry involuntarily concentrated on her breathing and in an instant she heard what the people at the bar were saying - although they were too far away for that to be possible. Igor felt a strange sense of relief, as if all the tension of the last months had drifted away, and a vision flashed before his eyes - not of a place, but of a particular person he had never met, and yet he knew he should find her. As the light returned, the four looked at each other. An understanding resonated in their eyes - something had just happened. For the next few minutes they talked nervously, trying to explain to each other what they had felt. Berry's mobile phone vibrated. A message from an unknown sender appeared on the screen: 'If you are reading this all at once, you must meet under the Świętokrzyski Bridge at midnight tonight. Everything will be explained on the spot." Outside, the night was sultry and the city seemed to be waiting - along with them.
