Aquarium (2021)

For as long as Lila and Adrian can remember they lived in a room, that has neither doors or windows, but instead a tube on the wall from which food appears daily. But after a strange light emerges from that tube one day and the food no longer appears, conflict arises between the two. While Lila wants to further explore and understand this foreign light, Adrian opposes it, partly because its presence seems to bring unforeseen dangers.
