Once called ‘the magic material', asbestos has become an invisible evil. In a forgotten valley of Switzerland, death, carried by the wind, forever and ever accompanies the everyday lives of the Italian asbestos factory workers. They are silenced by the Swiss industrial state. But the insides of their bodies bear witness to their story: their asbestos-injured lungs breathe in and out, intermingling with the repetitive industrial sounds, like heartbeats, in which they were once immersed. The binary rhythm of the Tarantella, a southern Italian ritual, once had the power to counter an invisible evil.
