Glass is a film about Eva, an East-European mother. When her son Mischa becomes ill, the costs of medical treatment are becoming a heavy burden on the family's finances. Due to recent events her husband Timur is unable to be employed, and all efforts to earn income is futile. When Eva is tipped to search for work in the Netherlands, she decides to take action. At her arrival in Amsterdam the situation proves not to be as expected. Eva is forced to accept low-wage jobs, and her employers are exploiting her. Then, somebody tells her about 'expensive glass': work at the red windows. Eva is frightened by this idea, but when she learns that Mischa's medical costs increase, she decides to give it a try. Her roommate Veronica, a prostitute, becomes a good friend and her lifestyle seems to be appealing. Eva's control on her life and grip on reality is gradually slipping away from her. Her plan works until she's is recognized by a Russian acquaintance Grigori. This leads to a dramatic climax: Eva is forced to make a choice and to risk everything she loves.
