Maya Carter detects a strange repeating signal during a routine deep-space observation. The signal contains coordinates that lead her to an unexplained location.

Maya and Ethan begin investigating the coordinates. Their search reveals that the location is connected to an abandoned communications project.

The team reaches an isolated Arctic research station. Inside, they discover old equipment that appears to have been receiving the same signal decades earlier.

Maya discovers classified documents describing an experiment designed to communicate with an unknown intelligence.

The signal changes unexpectedly and begins transmitting information about events that have not happened yet. Maya realizes that one of the predictions could occur within days.

Maya finally discovers the purpose of the transmission, but the revelation creates an even bigger mystery. The season ends with a new signal appearing from a completely different location.

A second transmission appears from an unexpected location. Maya compares it with the original signal and discovers a hidden pattern.

The team travels to an underground archive containing records of unexplained transmissions collected over several decades.

Maya discovers evidence suggesting that the signals may be responding to human activity rather than simply transmitting information.

A worldwide network of abandoned communication stations is discovered. Each station appears to be connected to the same experiment.

The signals begin counting down toward an unknown event. Maya and Ethan have only a limited amount of time to understand the message.

The team finds the original source of the transmissions and learns that the experiment was designed to establish communication with something beyond human understanding.

Maya must decide whether to shut down the communication network or continue the experiment and risk an unknown consequence.

The final episode reveals the meaning behind the signals. Maya sends one final response, creating a new mystery that could continue the story in another season. ## Awards The Last Signal received nominations for Best Science Fiction Series, Best Visual Effects and Best Cinematography.
