Rob begins work on 'Plan A' - finding out who Duncan's first love was and asking her to the wedding as his 'plus one'. But when he discovers that she's in a coma, Rob decides to track down his own high school crush, Nicola Dare. Further complications arise when a fun run, a tramp and a five-year-old girl are thrown into the mix, and Rob starts to suspect that Duncan is just better than him...

More than ever, Rob needs to find an impressive girl to show his ex what she has missed out on. Going out with your brother's girlfriend's sister was never the best way to find love, especially when you're dressed as a Panda.

Rob meets beautiful model/aspiring singer Aimee and manages to blag a date with her by telling her he's best mates with Jamelia — a lie that comes back to haunt him.

Rob decides to up the ante. The only way he can upstage his ex, Linsey, and Duncan from Blue in their celebrity magazine wedding pictures is by taking along a celebrity of his own. And who better than George Clooney's ex, Lisa Snowdon? But how can Rob get anywhere near her let alone woo her into being his 'plus one'?

After a catalogue of dating disasters, close shaves with the law and embarrassingly cringeworthy scenarios in which he has disgraced himself in front of celebrities and models, Rob decides to give up and avoid the wedding entirely. That is, until he hooks up with vivacious multi-millionairess, supermodel, biochemist, Astrid, who is just crazy for him.
