Young Calvin/Asa Butterfield works at an airport like his dad. He's a hypochondriac "with cancer". His doctor, after many consultations concerning different kinds of cancer that he doesn't have, recommends a cancer support group. There he meets Skye/Maisie Williams, a young woman, who also lives with her parents but otherwise quite different from Calvin. He helps her with her bucket list of things to do before dying (of cancer). She helps him with meeting and having a date with the cute, single flight attendant, Izzy/Nina Dobrev.
