This highly topical film centers on five suicidal people who meet on the Internet and form a "'suicide group". They all have reasons for which they want to die and arrange to meet at one of their member's homes to spend their last hours together. One of the women hastily kills herself in front of the others. The remaining four members decide to deal with their problems and live. Based loosely on an actual account that took place in Japan. Life, sex and redemption. "Ambiguous" also stars Nikki Sasaki ("Nurse Sisters", "Cuffs").
