In a town where soccer rules, Uncle Simon is obsessed with rugby. He has traveled to Wales to be a linesman and now he is secretly constructing a rugby pitch on the fairway of a golf course.

With only a few dark strands, Plants Don't Drink Coffee is a joyful and lighthearted celebration of life.

The offbeat plot elements are part of the attraction, however, along with the liveliness of Elorriaga's writing.
