Ryan Reynolds and Cailey Fleming star in this live-action/animated family comedy written and directed by John Krasinski. Struggling after the death of her mother, 12-year-old Bea (Fleming) gains the ability to see people's abandoned imaginary friends, known as IFs, and is moved to help them. She joins forces with her neighbour Cal (Reynolds), who shares the ability, in an attempt to reunite the IFs with the children who created and loved them but later forgot them.
