The player's character arrives at Aqua Lodge, a mountain fishing retreat operated by a man known as the Fishing Master. He has a history with this visitor: two years earlier, he found them unconscious outside a tackle shop, called an ambulance, and extended an open invitation to the lodge. Now they have come. The Fishing Master notes that the player's health has declined since they last met. He offers his own tackle and, having been a professional angler before a leg injury ended his career four years ago, volunteers to serve as their mentor. What follows is framed as both a fishing game and a story about recovery.
