Rent House of Fools (2002)

The inmates are running the asylum...literally. As a war led by local rebels surrounds their tranquil haven, the patients of a small psychiatric hospital remain blissfully cut off from the raging conflict, safely confined in their own small, restricted world. But problems ensue as the medical staff abandons the hospital, leaving the residents to fend for themselves. Janna (Julia Vysotsky), a beautiful young patient, takes it upon herself to organize the hapless group as best she can, entertaining them with her accordion and dreaming of the day when her imaginary fiance, pop musician Bryan Adams, will arrive to whisk her off to a better life.
