When a bad Shadow Bean makes it nighttime forever and makes all the citizens of Puddlebrook fall fast asleep, they must return it to the Pit of Shadows in the Cave of the Magical Bad Beans and get rid of it once and it for all. But, they must be careful and avoid the Bean Bats who lived there because if the Shadow Bean falls right into a Bean Bat's hand, darkness will spread across Puddlebrook forever, all the time. Meanwhile, some darkness-loving Bean Bats and Queen Batilda take over Puddlebrook with the help of Ms. Marmalady, who took some Bad Beans so she can sabotage Butterbean's Cafe; the Bean Team must find a way to start the day before it remains darkness forever.
