Film Thriller

When a fourteen year-old Richard sneaks his three friends through his father's hidden tunnel into the family's mining site, he only wants to impress them and witness the blasting of a new section. But one explosion changes everything. The earth trembles, the ground collapses -and the boys fall into a strange, ancient world buried deep beneath the surface. With no clear way out and danger lurking in every shadow, they must rely on each other, their wits, and a fierce will to survive. But this world isn't just earth and rock - it's alive, it's watching, and it might not let them leave.
