If It's Not Now, Then When? mostly takes place in an apartment inhabited by three members of a family (though never at the same time): mother Pearlly Chua (from Tsai Ming-liang's I Don't Want to Sleep Alone), daughter Tan Bee Hung and young son Kenny Gan. Their father seems recently to have died. The mother leaves early and returns late, out on long walks in the park with a lover whom the daughter and her best friend try to spy on.
