A 34 year old single woman, Nancy, hung-over again, exhausted by the endless fruitless set ups by her friends, traveling across London to toast another 10 years of her parent's successful happy magical marriage runs in with a 40 year old divorcee, Jack, who mistakes her for his 24 year old blind date. Nancy, deciding to go with it, happens to hop on the most chaotic yet hilarious journey of her life which neither of them will ever forget.

When yet another anniversary passes without a marriage proposal from her boyfriend, Anna decides to take action. Aware of a Celtic tradition that allows women to pop the question on Feb. 29, she plans to follow her lover to Dublin and ask him to marry her. Fate has other plans, however, and Anna winds up on the other side of the Emerald Isle with handsome, but surly, Declan -- an Irishman who may just lead Anna down the road to true love.
