Ep 1. Invasion of the Bane

In the season 0 premiere episode of the Sarah Jane Adventures, titled "Invasion of the Bane," viewers are introduced to Sarah Jane Smith, a former companion of the Doctor, who has now turned investigative journalist. As the episode begins, Sarah receives a mysterious package in the mail, which leads her to the company "Bane Enterprises." Posing as a potential investor, Sarah manages to sneak into the company and learns that Bane Enterprises is about to launch a new health drink called "Bubble Shock," which they claim will revolutionize the beverage industry.

Sarah's suspicions are raised when she sees that the workers at Bane Enterprises are acting strange, as if they are under some kind of mind control. Sarah decides to investigate further and enlists the help of a young girl named Maria, who has just moved in next door to her. Together, they break into Max Chambers' office (the founder of Bane Enterprises) and find evidence that the mind control is being caused by the ingestion of Bubble Shock. They also discover that the drink is not being made from "all natural ingredients" as advertised, but is instead being concocted with an alien substance.

With their investigation gaining traction, Sarah and Maria's cover is blown and they are captured by the company's security team. However, they are soon rescued by a mysterious man named Luke, who has knowledge of Bane Enterprises' true intentions. Luke reveals that he is an android created by a group of aliens called the Bane, and that Bane Enterprises is merely a front for their invasion plan. The Bane plan to use Bubble Shock to control and manipulate the minds of humanity, ultimately taking over the planet.

Sarah and Luke devise a plan to stop the invasion, which involves breaking into the Bane's spaceship and using Sarah's investigative skills to take control of the ship's computer. However, their attempt is thwarted by the appearance of a giant Bane monster. In a thrilling finale, Sarah, Maria, and Luke manage to defeat the monster and stop the invasion just in time.
