Following January’s film on Ireland’s offshore fishing industry, the latest episode of TG4 documentary series Tabú reaches into the heart and soul of the Irish Coast Guard — as told by the coastguard members in their own words.

In the aftermath of the loss of Rescue 116 and volunteer Caitríona Lucas, An Garda Cósta - Ár n-Insint Féin, which screens this coming Wednesday 4 March, explores how they continue to serve in spite of the tragedies.

Focusing on operations after the biggest tragedy that has happened to any Blue Light service in Ireland, the hour-long film reveals the anguish of the search, along with the coping mechanisms of “the coastguard family”.

And according to the producers, the documentary also reveals the dangers of the job and how they stay on the right side of risk.

Produced and directed by Darina Clancy for Midas Productions, Tabú: An Garda Cósta - Ár n-Insint Féin broadcasts Wednesday 4 March at 9.30pm on TG4.
