Maggie's Plan
2015

 Maggie (Greta Gerwig) and John (Ethan Hawke) fall head over heels in love, breaking up John's marriage to Georgette (Julianne Moore). The two marry and have a child together - but when Maggie eventually meets John's ex-wife, everything becomes clear - Georgette still loves John, John still loves Georgette and she, Maggie, is no longer in love with John!

If only Maggie could come up a plan to get her husband and his ex-wife back together...
