"The 100" official trailer has been released by CW and you will feel nothing but excitement as the fourth installment of the series debuts on February 1. In the post-apocalyptic drama's Season 4 premiere trailer, the group tries to thrive or survive, as tumultuous life on earth takes it toll on them.

Several scenes from "The 100" trailer include piles of bodies wrapped in ropes and cloth after exposure to a Nuclear Fallout. Another scene showed chilling pictures of irradiated humans falling miserably to ash and dust.

"The 100" Season 4 premiere entitled, "Death is Inevitable", is expected to have ground-breaking developments as the group fights a legion of enemies while in search of shelter away from the dangerous radiation that surrounds them. The group will be put to a test as they battle tooth and nail between saving and killing their own people in order to re-establish humanity. Justice and vengeance - two things that must be thrown under the bus, in order to thrive and survive.

In the "The 100" trailer, Erica Cerra's character AI A.L.I.E. said: "The nuclear power plants which the bombs tore down have started melting down and now, 96% of the earth is not livable. Black rain will ensue until there is no potable drinking water. Precancerous lesions will thrive. Death is inevitable."

She relayed it to Clarke Griffin, one of the initial roster of delinquents sent to the Earth to find out if the planet can be livable again after the nuclear apocalypse transpired. AI A.L.I.E. continued: "Let me help them with their pain, Clarke. We can save this race together."

Clarke responded and explained that pain does not go away easily, but in time, can be overcome. Aside from Eliza Taylor, Bob Morley, Marie Avgeropoulos and Isaiah Washington will be back for the next season of "The 100."
