Des larmes de métal tells the incredible epic of Fourchette, who suddenly finds himself endowed with life and movement following an... unfortunate accident. Immersed in a universe parallel to ours, she goes on an expedition, looking for other living objects like her. Throughout her setbacks, she will form new friendships, suffer betrayal, unmask plots in a world more hostile than expected, and, ultimately, try to save her skin... of metal.
