"One" is a song by American heavy metal band Metallica. It was released as the third and final single from their fourth studio album, ...And Justice for All (1988). Written by band members James Hetfield and Lars Ulrich, "One" is an anti-war song that portrays a World War I soldier who is severely wounded—arms and legs blown off by a landmine, blind and unable to speak or move—begging God to take his life. His only hope is to devise a way to communicate with the hospital staff. In the music video, he jolts in the hospital bed, spelling "Kill me" in Morse code. Production of the song was done by the band alongside Flemming Rasmussen. The song was the band's first top 40 hit single in the U.S., reaching number 35 on the Billboard Hot 100. It was also a number one hit in Finland.
