Ellen and Alexa have survived hangovers, dodgy landlords and most of their twenties together. But can they survive this?While nursing The Hangover from Hell, a flooded kitchen leads best friends Ellen and Alexa, and hapless housemate Jack, into their attic to turn off the water supply. But when Ben - Alexa's date from the night before - walks in, the door slams, the handle breaks and all four are trapped.

Cue the Worst Ever morning-after-the-night-before. As the hours tick by, Ellen nurses her sore head and watches as her best friend falls for this handsome stranger. Only for a horrifying realization to hit.

She is sure she knows Ben from somewhere. Frantically searching her memories, Ellen pieces together exactly how they've met before. Is Ben really who she thinks he is?And, most importantly, what on earth is she going to do about it .
