Penelope Keeling, a sixty-four-year-old daughter of a famous artist, reflects on her life, and the fate and choices that defined it, when she arrives in the Mediterranean to stay with her headstrong daughter. Shifting through time, and falling into place like the pieces of a jigsaw, the truth of Penelope's rich, heartbreaking and surprising life unfolds.
Unfortunately the movie The Shell Seekers is not yet available on HBO Max.
