THE INVASION OF THE ULTRA BODIES

Unos microorganismos de un lejano planeta han llegado a la Tierra. Matthew trabaja como funcionario en el departamento de sanidad de la ciudad de San Francisco. Elizabeth, una colaboradora suya por la que siente algo más que admiración profesional, le cuenta que su marido ha experimentado una transformación tal que le resulta irreconocible. Matthew se lo toma a broma, pero ese mismo día observa que también otras personas sienten el mismo recelo hacia sus parejas o amigos. Matthew Bennell notices that several of his friends are complaining that their close relatives are in some way different. When questioned later they themselves seem changed as they deny everything or make lame excuses. As the invaders increase in number they become more open and Bennell, who has by now witnessed an attempted «replacement» realises that he and his friends must escape or suffer the same fate. But who can he trust to help him and who has already been snatched?
