In 2014, a terrible nightmare became real for Tom Madsen and his wife Marilene: a lump on their son Kevin's leg was diagnosed as sarcoma. Kevin soldiers on through debilitating treatments for three years, but finally passes just shy of his 20th birthday. But Kevin refuses to go away, and he has shown up in numerous ways since he passed. In Relentless: From Both Sides of the Veil, the Madsen father and son show that our love for each other transcends our physical bodies. And Madsen the father becomes the student, as his son reaches across the veil to show his father - and many others - that love and spirit survive.
