Julia and Tomás are together. They don't exactly know how, though. They spend their day in an apartment; alone, but not completely. Through the eyes of three different directors in different moments of the day, the two of them do their thing, waste their time and have adventures. Julia wants vacations on the beach but Tomás is afraid of jellyfish. He believes she is cheating on him, but also has secrets of his own. And a nervous neighbor ends up causing more trouble than they would have thought. Morning·Afternoon·Night: three filmmakers, two characters, and one couple in one single day.
