Meet Rachel Summers: a twenty-something make-up artist whose life is very much going to plan. She has a job she loves, a lovely long-term boyfriend, a great flat in north London and some fabulous friends. The next phase in her masterplan is to buy a house, have a baby, move to a bigger house, have another baby, get a 4x4. Simple.
Well, not quite as Simon, Rachel's boyfriend, suddenly decides that they should take a break. Rachel's convinced it's just a three-year itch but, four months later, they are still living under the same roof but sleeping in separate bedrooms.
It's time for an intervention as Emilie and Matthew, Rachel's best friends, can no longer bear to watch Rachel suffer anymore. As they try to convince her to move out and move on, they come up with the ultimate break-up cure - the single girl's to-do list. A list of of all the things Rachel should see and do in her newly single life.
But nothing could have prepared them for the hilarious adventures that are about to unfold as the to-do list takes them around London and abroad, and proves to them all that love is out there if you're willing to take a chance on it ...
