When introverted Ethan Fawcett marries fun-loving Barb, so comfortable in the world, he has every reason to believe he will be delivered from a lifetime of solitude. She fills his world with a sense of adventure, expanding his horizons beyond his comfortable routine. To ease Ethan’s fears of becoming a father, Barb suggests they foster two young brothers, Tommy and Sam, and Ethan immediately falls in love with the boys. When the pandemic hits, he becomes obsessed with providing a perfect life for them. But instead of bringing Barb and Ethan closer together, the boys become a wedge in their relationship, as Ethan is unable to share with Barb a secret that has been haunting him since childhood. Then Ethan takes Tommy and Sam on a biking trip in Italy, and it becomes clear just how unusual Ethan and his boys are.
