When news of the Titanic first broke, headlines falsely claimed all had survived. In truth, over 1,500 lives were lost on April 14th, 1912 – a reality revealed only through the Marconi wireless messages received by the RMS Carpathia, the only ship that came to its rescue. Why didn’t the nearby SS Californian respond? Why did Titanic originally ignore iceberg warnings? With lifeboats for only half aboard, the Titanic’s wireless operators were its final lifeline. This poetic documentary brings their messages to life: Titanic’s final heartbeat as the Carpathia rushed to resuscitate it.
