The Welts (2004)

Following the death of his mother in '80s Poland, 12-year-old Wojciech has taken the brunt of his stressed father's frustrations with him; the boy frequently gets punished via belt. Wojciech's father occasionally tries to, instead, bond with him, but soon snaps back to his short-fused habits. Apart from Wojciech's friend Bartek, no one does anything to help. Jump to present day, Wojciech is a furrow-browed journalist who spends most of his spare time spelunking alone. Just like his father, he has serious anger management issues. Fellow caver Tania feels inexplicably attracted to him, but the love of a good woman may not be enough.
