Greg Heffley's school is holding a Valentine's Day dance, and it's turned his world upside down.

It's every man for himself as everyone scrambles to find a date for the big day, and Greg WON'T be left partner-less.

His best friend, Rowley, doesn't have any prospects either but that's a small consolation...

To make matters worse, his Uncle Gary has moved in and is taking over the whole house.

Will Greg be lucky in love, and get his house back?
