A single day at the beach unfolds into a quiet tapestry of memories, unspoken regrets, and small acts of hope. As Sarah watches her young son, Tommy, build sand art that the waves endlessly erase, she navigates her own shifting emotional tides-grief, co-parenting tensions, and the lingering warmth of a love that's become distant. "Sand and Salt" is a gentle, reflective snapshot of what it means to hold onto the moments that slip between our fingers like grains of sand.
