After a plane crash in which they seem to be the only survivors, Linda Liddle (Rachel McAdams) and Bradley Preston (Dylan O'Brien), two coworkers with a relationship marked by past disagreements, wake up on a deserted island with no means of communication or possibility of rescue. The situation, seemingly desperate, forces them to join forces to survive, sharing scarce resources and facing a hostile environment that tests both their physical endurance and emotional stability.

As they try to organize their day-to-day lives and maintain hope of being found, their coexistence begins to reveal old resentments and unresolved tensions that resurface with unexpected intensity. What initially seemed like a necessary alliance gradually transforms into a power struggle where trust erodes and every gesture takes on a double meaning. Raimi places the narrative in an ambiguous territory where cooperation and manipulation blur, and where survival depends as much on intelligence as on the ability to dominate the other.

With a tone that combines psychological suspense with moments of dark humor, Send Help (Enviad ayuda) turns isolation into a laboratory of extreme emotions. As the tension rises, the viewer witnesses a duel of wills between two characters pushed to their limits, in a story where the instinct for survival reveals the most complex and contradictory facets of human nature.
