Follows the ordinary men and women who volunteer with the Royal National Lifeboat Institution (RNLI), risking their lives every day to save others who are in danger. With bases across Britain the RNLI are prepared to attend rescue calls around the clock and in any weather condition. Operating for more than 150 years, the organisation has saved over 140,000 people from life-threatening situations out at sea. During the winter months the elements become treacherous posing more risks to people venturing in the harsh waters, in turn increasing the number of challenging rescue missions for the brave volunteers.
