Director Geertjan Lassche follows top athlete Michel Butter and his trainer in the mental tunnel of concentration before, during and after the marathon. Lassche gets the unique opportunity to capture one of the toughest sports in the world from the inside during the Amsterdam Marathon. Michel Butter, the third Dutchman ever to run a marathon under 2 hours and 10 minutes, has been trained by Guido Hartensveld for 15 years. They had many highlights, until Michel was hit by a serious injury in 2013. He and his coach fight back, both physically and mentally. The Amsterdam Marathon should be the culmination of a long process, with a come back from Michel at the top and a qualification for the Olympic Games as a reward.
