Two elderly buddies, one with dementia and the other with heart issues, go on a road trip to the Ark Encounter. They face hurdles, exchange identities, strengthen their friendship while reaching their goal.

Jon Koski, a 69-year-old battling early dementia and living in a mobile home park in Michigan, flees his children's attempt to send him to a nursing home. He teams up with a new friend, Miller Gibbs, an endearing 64-year-old with a weak heart, aiming to visit Kentucky's Ark Encounter, a full-scale replica of Noah's Ark. As they traverse Ohio, the bantering begins as Gibbs calls out Koski's paranoia, testing their friendship. They swap cars, license plates, and routes through the countryside to avoid capture. Can they reach the Ark without getting caught? Will clashing morals break their bond, and will Gibbs' heart hold out as the road to triumph is paved with unexpected challenges?
