Watch FilmoFlix. The short film "Desire" shows a relationship; just as John Lennon fell in love with Yoko Ono at first sight watching her perform, so do characters 1 and 2 in the film. The red plastic bag in the film represents the hearts of these two characters. Such an abstract object does not need to be explained during the course of the film because the characters understand each other. This bag represents our common heart.
