Plus One is a British sitcom written and created by Tim Allsop and Stewart Williams, originally broadcast in 2007 as part of Channel 4's Comedy Showcase, before a full five episode series was commissioned and began transmitting on 9 January 2009.
It centres itself around a "record producer" (of music compilation albums) Rob Black (Daniel Mays), whose girlfriend (Miranda Raison) has dumped him to marry "Duncan from Blue".
In an attempt to impress Nicola Dare (Susie Amy) - his own first love - after having insulted her transgender brother, Rob decides to participate in the fun run himself.
Enter Rich - Rob's brother - and his girlfriend's sister, Abby (Sophie Winkleman); a gorgeous West End star who always has to have what she wants.
He convinces her to set up a photoshoot with model Aimee, who becomes more and more attracted to him when Laura tells her all the celebrities he has allegedly worked with, including mentioning that Rob and Jamelia are 'practically best friends'.
His brother, Rich, offers his assistance with one of his pupils, Craig, who pretends to be disabled - for a price of money and video games - to get Rob in with Lisa.
An allergic reaction to peanuts on Craig's part leads to Lisa having to leave the date early but scheduling a lunch appointment with Rob the next day.
After a catalogue of dating disasters, close shaves with the law and public disgrace in front of celebrities and models, Rob decides to give up looking for the perfect plus one to outshine Linsey and Duncan.
However, before long he meets the beautiful Astrid (a millionaire, supermodel, biochemist whose dad invented Toilet Duck), and they quickly fall for each other.
