Kamikaze (2014) on Netflix

Plot summary

Slastan comes from Karadjistan, a fictional country in the Caucasus. He arrives in Moscow with a bomb and one plan: to blow up a plane bound for Madrid and himself with it. A snowstorm grounds the flight, and he and everyone else booked on it are put up in a hotel until the weather clears. The 332 people he intends to kill are in the same building, Spaniards among them, and the delay keeps him from his mission. While the storm lasts, he gets to know the people around him and speaks with them through the days the plane cannot leave.
