Welcome to the neon-lit, muzak-drifting world of Shelfstackers and the endless shift of four teens on the bottom rung of the supermarket pecking order. Banter, pranks, racing customers - any outlet for brimming frustrations is fair game. There's only one rule: don't get fired. When ex-boy band member Dave starts at Grogan's, the girls are instantly smitten with his chat of gigs, fame and his top forty classic Scorpio Nights. The boys however are slightly less enamoured, especially Dan, who makes it his mission to try and undermine Dave at every turn. When his efforts fail, Dan's left reeling when he discovers Dave has intentions towards Dani. As Dani and Dave walk off for a 'Scorpio Night', Dan is left confused by his feelings. Is he jealous? Jealousy seems to be the theme of the day as Fitzy grows increasingly irritated by Yakiv, a Ukrainian boy who turned up on Roy's doorstep that morning and who Roy has assumed is his son. As Roy indulges the non-English speaking Yakiv in father and son bonding activities, Fitzy is in a race against time to learn Ukrainian and unmask Yakiv's true identity.
