Abigail is a young woman in her twenties who has recently lost her parents and moved to Chicago to share an apartment with her estranged aunt, to whom she pays rent and rarely speaks. She is troubled by sleeplessness and nocturnal visits from apparitions. When her aunt suddenly dies, the distinction between reality and dream dissolves. The only person who understands her is Hector, a young man from Colombia with a fatal illness who's lost all hope and just needs a place to stay.

Pushed to the breaking-up point after their latest 'why can't you do this one little thing for me?' argument, Brooke calls it quits with her boyfriend Gary. What follows is a hilarious series of remedies, war tactics, overtures and undermining tricks – all encouraged by the former couple's friends and confidantes …and the occasional total stranger! When neither ex is willing to move out of their shared apartment, the only solution is to continue living as hostile roommates until one of them reaches breaking point.
