M/Other

M/OTHER centers on a seemingly stable relationship at the moment when it starts to come apart. Tetsuro, owner of a chain of elegant, loss-making restaurants, is recently divorced; his ex-wife has custody of their eight-year-old son, Shun. Tetsuro now cohabits with a younger woman, Aki, a graphic designer. When Shun comes to stay for several weeks (his mother is in hospital with a broken leg), Aki finds herself cast as his surrogate-mother-- or is it that she unconsciously casts herself in the role, to measure herself against the absent ex-wife?
