Morty Smith Prime, also known as Morty C-137, had been abandoned by his grandfather, Rick C-137, who had decided that two crows were more valuable than his grandson. The fourteen-year-old boy was determined to find a way to get his grandfather back, but he was unaware that Rick C-137 had been on a hunting spree while he was away. Meanwhile, Rick Sanchez Prime had traveled to a different dimension in search of his original Morty, showing no concern for his family. However, he discovered that his original family had been killed and that Rick C-137 had been acting as a grandfather to Morty, not just any Morty, but Rick Prime's Morty. As Rick Prime observed Morty, he realized that Rick C-137 was not around to prevent him from reclaiming his grandson. Rick Sanchez C-137 enjoyed living his life on his terms. He missed Morty, but he believed that they should no longer be partners. He tried to put Morty out of his mind and hoped the boy would stay out of trouble. However, Rick's sense of security was shattered when Summer informed him that another Rick had kidnapped Morty, not just Rick, but Rick Prime himself. Now, Rick was determined to abandon his new life and save his grandson from the man who had killed his own family. He knew that the stakes were high, but he was willing to take on any challenge to rescue Morty from the clutches of his grandfather.
