A small military-occupied community sits, waiting, parched of natural water while nearby levees hold the rising global shoreline. Seventeen-year-old twins Alix and Evan pass the time in an empty, abandoned pool with what they are able to scavenge from the abandoned houses, while government official Portia returns to familiar places, her past colliding with the present. The planned evacuation notice that eventually reaches all cities has finally come, but the twins learn that survival is not guaranteed. As they rush to reach their grandmother, a retired journalist now living with dementia, her snippets of memories flow like humanity's record player, skipping tracks before the final flood.

A non-linear poetic play that acts like a postcard from the future, Shorelines is about family and community in a world ravaged by climate change. It also speaks to the inevitable inequality of disaster response and how poorer communities are disproportionately affected by it. Mishka Lavigne's message within her lyrical piece is urgent and multi-dimensional: it is a reminder that all things are connected and hope can only lie in the relationships we form with the people around us.
