The fearless and determined Sam is a young Maori girl on a mission to win her battle with cancer. She hopes to find strength under the watchful eye of Taranaki Maunga, or Mountain, and so embarks on the adventure of a lifetime. Sam meets some ragtag misfits along the way – the lonely yet adorable Mallory, hoping to find friends, and the fierce Bronco, a runaway from a father who is too busy to notice him. As they go off-the-beaten track, trekking through spectacular New Zealand landscapes, the trio learn the magic of adventure and true connection.
