Toby (2019)

On the surface Gerty and Matthew seem like the quintessential quaint old British couple, but Gerty has a thirst for vengeance. This one act film has Gerty invite her young neighbour Rodney for tea, but unbeknownst to her that is the last person Matthew wants to see. They discuss the passing of their sweet dog Toby and eventually Gerty's motives become clear.
