Vektor is a 2010 Croatian post-apocalyptic drama/thriller film, produced and directed by Ivan Rogar and written by Josip Facković.

Described as the "first Croatian post-apocalyptic film",[1] Vektor is presented almost in black and white, and favors drama and a dark atmosphere over outright violence.

After receiving a distressed phone call, Christine returns to her childhood home, hoping to find her father alive, accompanied by a lifetime friend and a secretive scientist.

Strange things start to happen after they find a woman named Elena, amnesic and spattered with blood.

[4] Debi Moore of Dread Central thought of the film as "chillingly topical and timely" in the wake of the Fukushima nuclear disaster, with a blurred "line between fantasy and reality".
