After a strange thunderstorm, Tee Zeng finds a talking sock at her mom's laundry and decides to call it 'Kung Fu Sock.' Kung Fu Sock claims to be a Kung Fu master from another world, where he guarded an ancient scroll.
It's all over the news that Sword Hero of the nearby island has saved a ship. This catches Kung Fu Sock's attention, and he wants to meet the superhero.
