He hangs out on the Côte D'Opale and attends meetings of the Nationalist Party with his childhood friend Fatso (Julien Bodard). His old love, Eve (Lucy Caron), has abandoned him for Corinne (Priscilla Benoist). When a strange magma is found near the town, the inhabitants suddenly start to behave very strangely. Our beloved heroes Captain Van Der Weyden (Bernard Pruvost) and his loyal assistant Carpentier (Philippe Jore) investigate and quickly begin to suspect an alien attack. The Extra-Human invasion has begun!
