Rob’s girlfriend has left him… for Duncan from Blue. Now they’re getting married and to make matters worse – they’ve invited Rob to the wedding. Rob is out to settle the score; he MUST find a girl who is comprehensively more impressive than Duncan to accompany him to the nuptials in a bid to outshine the happy couple. Rob’s quest knows no bounds; he bribes a child in order to win a date with Lisa Snowdon, persuades singer Jamelia to be his best mate, humiliates himself to bag a date with a West End superstar, and inadvertently gets branded a pervert (twice!) while trying to impress his first love. Rob’s receives little encouragement from his brother Rich (Nigel Harman) and his sister Rebecca (Ingrid Oliver). Even his friends Paul (Steve John Shepherd) and Laura doubt his pulling power. Will Rob ever find his perfect Plus One?
