TRASH takes place entirely in a dump - a municipal landfill, where two estranged sisters have come to look for a letter from their mother. They've come from their mother's funeral - the first time they've seen each other in years, and as they dig through the literal and metaphorical trash heap, they get further and further into their complicated relationship - and with the lives they led under the shadow of a domineering mother who still controls and influences them even after her death.
