One of these swimmers is Alice, who is slowly losing her memory. For Alice, the pool was a final stand against the darkness of her encroaching dementia. Without the fellowship of other swimmers and the routine of her daily laps she is plunged into dislocation and chaos, swept into memories of her childhood and the Japanese American incarceration camp in which she spent the war. Alice's estranged daughter, reentering her mother's life too late, witnesses her stark and devastating decline.
