Our take

Scientists on a billionaire's private island try to talk to alien intelligence, then the project spirals into chaos. Frequent strong language, a brief shooting with blood, drug talk and a child injury scare sit inside the mystery. Fine with a parent from 15. Younger teens who dislike alien dread or seeing a kid hurt should skip it.

Uplifting themes

It asks what responsibility comes with first contact and curiosity A young scientist keeps pushing for answers when adults turn reckless A light primer on listening for alien signals and the risks of answering

Story (may spoil tone)

A computer scientist is invited by a tech billionaire to join his private facility on a Caribbean island to investigate extraterrestrial matter on Earth. When they make contact beyond our world, chaos erupts as we’re left to wonder: do they come in peace?

Talk after watching

  • If we could talk to another intelligence, should we answer before we understand the risk?
  • Who should decide when a breakthrough is too dangerous to push further?
