When Tara and Sophia plan an Icelandic vacation they seek waterfalls, relaxation, and adventure. But something sinister awaits along its craggy shores. Deep in the heart of the mountains, Doctor Anri Pyke works to uncover history’s greatest mystery, yet his unconventional methods have ostracized him from the scientific community. Haunted and fueled by the dark days of his past, nothing will stop him from cementing his revolutionary discovery.

While trekking through the picturesque Nordic island, the two women struggle in an increasingly turbulent relationship. Tara’s life is changing and Sophia wants only for things to remain the same. Plagued with secrets and turmoil, they find themselves on a collision course with the most profound, and dangerous, experiment known to man.

21 Grams follows Anri’s shocking path to answering one of humanity’s oldest questions-does a soul exist, and if so, can it be proven?
