In 2004 Maggie Lane fell to her death from the cliffs at Beachy Head. While trying to come to terms with this tragic event, her husband, Keith, sought solace by going back to the spot from which she had jumped. It was whilst visiting the cliff top that he saw a woman about to throw herself over the edge - Keith took the time to persuade her not to do it. From this moment onwards Keith made it his mission to patrol the area in the hope of saving lives. In four years Keith has saved 29 people from committing suicide at Beachy Head - even climbing down 15ft over the edge to rescue a woman who had slipped having changed her mind about taking her life. Dedicated and determined, Keith tells of his own personal despair and how, in his darkest hour, he wanted to end it all, but found a sense of purpose in helping those in desperate need. Keith also divulges why after much reluctance he has been forced to give up his vigil.
