This surf documentary includes authentic, unscripted dialogue from its participants. Viewer discretion is advised for strong language.

A rare monster wave, appearing only on the most violent of winter swells, breaking off Ireland's wild west coast.

When a once-in-a-blue-moon forecast lit up the charts, big wave legend Andrew Cotton teamed up with the UK's most exciting young chargers, Ben Larg and Louis Thomas-Hudson, for a strike mission, or ‘Misean Tobann’, to hunt down this phantom wave.

This is the story of that mission. Battling brutal Atlantic conditions, freezing water, and the unknown, the team puts themselves on the line to ride this Irish secret. Is the reward worth the risk?
