"Secret of the Cave" tells a story of Roy, a young American male, who spends the summer at a western Irish fishing town. After some time, strange activities begin to pop up, as well as rumors of a spectral invasion. While initially scatter-shot, things start pointing toward a nearby cave. Roy plans to dispel the rumors and investigate the cavern with his teen friends Oscar and Abbey. While Roy eventually learns the truth behind the cave, he doesn't leave it as the same Roy who entered. "Secret of the Cave" is a student film adaptation of Arthur Maxwell's children's book.
