Thoughts about walls

A man in a light-colored coat crawls over a rocky shore littered with seals, with the ocean and waves visible in the background. The scene cuts to a dark, rainy night where a car speeds through an open gate, followed by a shot of a figure behind bars in a dimly lit room. The sequence ends with a bright flash revealing a woman and a child standing in a field, then cuts to a man in a white coat behind a barred window.
