Turns out, sex isn't everything. After a misspent night with a hot model (and a little too much booze), Rinko wakes up feeling more depressed than ever, unable to shake her growing suspicion that, at 33, she's doomed to be forever alone. Her friends Kaori and Koyuki think they have found cosmopolitan bliss in an unavailable ex and a married man, but the daylight only brings increasingly devastating "what-ifs." And with younger, fitter, hungrier women entering the ring, these three will have to brawl their way to the win...or risk throwing in the towel for good.
