The Legend of Korra season 4 will return this Friday, 5 December, with episode 10 titled Operation: Beifong.

As the title suggests, the Beifong family, in the upcoming episode, will unite to save their clan from Kuvira and her evil intentions.

In the previous episode Beyond the Wilds, Opal and Lin seek help from Bolin to execute a risky mission to the metal city of Zaofu in order to rescue her family who are being held captive by Kuvira.

However, during their journey they will meet the most unexpected person, Toph, Opal's grandmother and Lin's mother.

Meanwhile, Kuvira is still busy harvesting the ancient spirit vines from the swamp, the place that Toph called her home.

Now Kuvira needs to realise that she has angered Toph and this may not be good news for her as the greatest earthbender ever would love to get into action.

In Operation: Beifong, Lin, Suyin, Toph and the other remaining members of the Beifong family will join the forces to bring down the show's antagonist.

The Book 4: Balance is based on the spin-off of Avatar: The Last Airbender and promises to bring high-end action back as there are only four episodes left for Korra to end.

Hypable suspects that the series will end with a prominent character's death and the website weighed in on the old Toph's sad end.

The Legend of Korra book 4 Balance episode 10 will start streaming on Nick.com this Friday, 5 December.
