Ep 9. Mona Lisa's Revenge, Part 1

In Sarah Jane Adventures season 3 episode 9, titled "Mona Lisa's Revenge, Part 1," Sarah Jane and her young companions find themselves dealing with a very unusual situation. It all starts when new art teacher Haresh Chandra takes his class on a trip to the famous Walker Art Gallery in Liverpool. Among the many paintings on display, the students are particularly drawn to one in particular: the Mona Lisa.

But this is no ordinary Mona Lisa. The painting seems to be alive in some way, with its head turning to follow people around the room and its eyes appearing to glow with an eerie light. And when Rani investigates further, she discovers that the painting is, in fact, a fake - a cleverly crafted forgery that has somehow come to life.

As the team begins to investigate, they uncover a sinister plot involving a group of art-restorers who are using a strange alien technology to bring paintings to life and steal them for their own nefarious purposes. Not only that, but they soon realize that the Mona Lisa is only the beginning - and that there are many other paintings out there that are also in danger of being stolen and brought to life.

With the help of a mysterious stranger who turns out to be a former member of UNIT, the team sets out to stop the art-restorers and put a stop to their plans. But with the Mona Lisa now on the loose and wreaking havoc in the streets of Liverpool, they are running out of time - and it soon becomes clear that they may have to make some difficult sacrifices in order to save the day.

As always, the episode is full of action, adventure, and plenty of surprises, as Sarah Jane and her young companions face off against yet another dangerous threat from beyond the stars. With a thrilling storyline, great performances from all the cast, and plenty of special effects to keep things exciting, "Mona Lisa's Revenge, Part 1" is a must-watch episode for fans of the series and anyone who loves a good science fiction adventure.
