Signal One

Signal One follows Dr. Annika Cask (played by Isabelle Fuhrman), a brilliant computer scientist known for groundbreaking work in astrophysics. She is recruited by a tech billionaire (played by Dennis Quaid) to join a secret research project on a private Caribbean island. The project centers on a device called LITTLEMOUTH, created by eccentric physicist Perry Glassner (played by David Thewlis), which is designed to communicate with extraterrestrial intelligence.

As the team begins receiving and transmitting signals beyond Earth, they realize they may have achieved humanity's first contact with an alien civilization. What starts as a scientific breakthrough gradually becomes a crisis as the incoming communication appears to have profound and potentially dangerous effects on the researchers and the facility itself. Questions emerge about whether the intelligence is friendly, hostile, or simply beyond human understanding.
