Silvia是一名对芭蕾舞充满激情的舞者。为了让自己的舞姿达到完美，她决定一连几天把自己锁在家里排练。这种强迫症让她精神错乱，夜不能眠，寝食难安。

Silvia is a ballerina completely consumed by dance. Determined to rehearse until she achieves perfection, she locks herself in her apartment for days in a row. Her compulsion makes her enter a state of growing delirium, unable to sleep and hardly eating.
