"The Third Party" is a Filipino romantic comedy that follows three roommates who probably shouldn't be sharing the same roof under normal circumstances. The movie starts out when Andi, a hopeful fashion designer, decides to track down her ex-boyfriend Max with the intention of winning him back for good. Unfortunately, her plan doesn't quite pan out, as Max is now in a committed relationship with a man named Christian. In an even more unfortunate turn of events, Andi's financial situation forces her to move in with her ex-boyfriend and the man he's now in love with.
