During the reign of the Empire, a rabbit-like alien slave named Lop escapes her captors on the planet Tau and is discovered by the planet's clan leader Yasaburo and his daughter Ochō, the latter of whom convinces the former to adopt Lop as his daughter. Seven years later, the Empire has occupied their planet and is exploiting it for its natural resources; Yasaburo wants to drive the Empire off their planet, while Ochō wants to cooperate with the Empire. After failing to convince Yasaburo to join her, Ochō enlists in the Imperial navy despite Lop's protests. With Ochō gone, Yasaburo passes down the family treasure, an ancient lightsaber given to their ancestor and passed down the generations, to the Force-sensitive Lop, and departs to confront Ochō. Ochō blinds Yasaburo in a fight, but Lop arrives and injures Ochō, who is forced to flee. Lop then vows to return Ochō home.
