Samurai Jack - Season 5 Episode 1 -

It's been 50 years since we last saw Samurai Jack and time has not been kind to him. Aku has destroyed every time portal and Jack has stopped aging, a side effect of time travel. It seems he is cursed to just roam the land for all eternity. His past haunts him as well as a cult of assasins dedicated to killing him for Aku's glory.
