When a South Florida trailer park is slated for closure by its owner, the evangelical TV network TBN, residents have until the end of the year to fight the eviction or find new homes. "Last Days on Lake Trinity" chronicles this struggle, while painting an intimate portrait of friendship between three colorful older women who are longtime residents of the park. The film captures the profound loss of a singular community amid a growing affordable housing crisis that increasingly threatens older adults with homelessness.
