A girl living in a lighthouse knows exactly when summer ends, knows she has to leave, and spends her final weeks trying to figure out who she'll be when she's gone. The movie compresses that countdown into something sharp: three people searching for purpose in the time they have left, not to save the world, but to know themselves before they scatter. Summer Pockets earns its ache because it's about the ordinary terror of growing up, the moment when "what do you want to do with your life" stops being theoretical and becomes urgent.
Tsumugi lives in isolation atop a lighthouse on a quiet island, her days defined by routine and solitude. When summer arrives, so does Hairi, an unexpected visitor whose presence disrupts the careful rhythm of her existence. As the season ticks away, Tsumugi faces an unavoidable truth: she must leave this place when autumn comes, returning to the distant life waiting for her beyond the island's shores. Determined to make the most of her remaining time, Tsumugi sets out with Hairi and Shizuku to chase something she's never quite found: purpose. What starts as a simple summer adventure becomes a quiet meditation on identity and belonging. The three search through ordinary moments, conversations, and small discoveries, all while the clock counts down toward inevitable change. Woven throughout is a subtle supernatural thread that blurs the line between memory and reality. The film balances melancholy with hope, asking whether some connections are powerful enough to anchor us, even when the tide pulls us away. It's a story about finding yourself in the time you have left.
