*On Earth Prime, Quinn's Father died when he was 11 or 12 (I have a feling this depends on the episode used as a reference) and he was brought up by his mother after that.
The Sliders start off in a normal San Fransisco streed. They enter the vortex behind a building and exit in almost exactly the same place. they look around, but it is all abandoned.It wasn't the Kromaggs that did this - not showy enough. The Sliders are stuck there for a week. Quinn gets attacked by some dogs, but Maggie scares them away using a gun she found in a police car.

They go to Quinn's home. They see all the trophies Quinn wanted to win, but didn't. they also find photographs. They discover that on this world it was Mrs. Mallory who died when Quinn was little and this world's Quinn was brought up by his father. They go to the basement in the hope of finding something useful, but it is all smashed up. They go outside and another Quinn creeps up behind Maggie. It turns out he slid everyone off this world when an anti-gravity device he was testing went wrong 3 years ago. He created a "Slidewave" and was in the eye of the storm, which was why he wasn't also sent. Quinn wants to get the people back. Quinn2 looks for schematics with Maggie and she finds his father's Nobel Prize. They all go to an electronics store to find the necessary pieces for the slide machine. Quinn2 doesn't believe our Quinn's plan will work. Quinn picks up a biomed scanner which he can adapt so that the right people are slid of the world.
They build the machine which turns out smaller than our Quinn's original, but larger than Quinn2's original. They open the vortex using the new machine and they take it with them. Maggie takes a gun. They exit in a basement room (poss. Quinn's eqiv.) Quinn discovers that the slidewave must have damaged the pathway between the worlds as a burn mark is left on the wall from their vortex. A boy comes down and sees them and then runs back up the stairs again. They follow him up to a VERY crowded house. 2 nuns who are duplicates are in charge. They are taken to a room and interrogated. As usual, their story is not believed. They find out that 3 years ago all the people on Quinn2's world were slid there and 5 billion people became 10 billion and now all those mouths cannot be fed properly. Quinn2 admits that he sent them all there. He turns on the machine as a kind of proof and someone throws water on it. Instead, they produce money to prove that they are telling the truth and that they are not raiders looking for food.
The two Quinns argue over the machine and what Quinn2 did, but together they start to rebuild it. They find that there is a strict curfew on this world and that this world is ruled by powerful warlords. They go to an electronics store to get more parts. Maggie's gun is taken from her. They get what they need and start back. Quinn2 wants to work with Quinn on another sliding machine (or something else) when they get back to Quinn2's world. Quinn doesn't want to and they end up arguing about morals. Police start shooting at them, so they run and Quinn2 is left behind. Quinn goes back for him and they escape. Outside, that night, Quinn2 and Maggie talk.
Inside, Quinn gives a speech about how another slidewave will permernantly collapse the pathway between the two worlds. Sister Celine says that they must send everyone back, even though she enjoys having her double around and the world has moved on, so that there will be enough resources to survive.
Sister Celine introduces Roberto to the Sliders who will show them where to get enough power to create a Slidewave. The only place where there is enough power to to this is at the generators in the local warlord's fortress. Roberto lost a job there because he wouldn't kill a friend.
They go there and are captured by the Boss'(Name given to local warlord) men. They are taken to the Boss and questioned. All except Roberto are put into a room. Quinn2 still wants to work on a better machine with Quinn, but Quinn says there are more important things than science. They are taken back to the Boss who is planning to shoot the machine to pieces because before he came to this world he was a noting and he doesn't want his power to end. Quinn intervenes, so the Boss decides to shoot him first instead. Quinn2 jumps in front and takes the bullet in the right arm. They escape and get to the generators. They connect up the slidewave device. The Boss' men catch them up and they are shot at. Roberto is hit so Rembrandt hits the power and the Slidewave goes out. They end up back on the previous world. The Sliders invite Quinn2 to come along, but he declines. He then asks Maggie to stay, but she won't because of Quinn. They Slide.
