The Season 4 cast. From left to right: Rembrandt Brown, Quinn Mallory, Colin Mallory, and Maggie Beckett
In Season 4 of Sliders, after three months and ten worlds, Quinn Mallory and Maggie Beckett finally follow the trail of their friends; but the world believed to be home has changed since Quinn and Maggie's last visit. Now conquered by the Kromagg Dynasty, this world found Rembrandt Brown sent to the horrors of a Kromagg prison and Wade Welles sent to a Kromagg breeder-camp on an alternate Earth. Soon captured himself, Quinn finds his imprisoned mother who tells him that he is, in fact, her adopted son, and is actually from another, parallel world - the Earth on which the Kromaggs originated. With the help of the local resistance, Quinn, Maggie and Rembrandt escape with the goal of finding Quinn's long lost brother who holds the key to locating the Kromagg homeworld and the weapon that can free Earth Prime.
They find Quinn's brother Colin on another world, their parents having sent them to different worlds for their protection after their home was attacked by Kromaggs, which was no longer safe. Colin becomes the sixth Slider, and they try to track down their birth-parents, hoping they have the answers they seek, and the means to defeat the Kromaggs. This war with the Kromaggs is the primary theme throughout the season.
