Jack traded his dog Trigger for magic beans with an old man after Trigger got injured. Jack's mother threw the beans outside, and overnight a gigantic beanstalk grew. Jack climbed the beanstalk and encountered a giant and his wife. Jack took the giant's guitar and chopped down the beanstalk, causing the giant to fall to his death. Jack used his new guitar skills to earn money, allowing him to buy Trigger back and support himself and his mother.
