IF

A young girl who goes through a difficult experience begins to see everyone's imaginary friends who have been left behind as their real-life friends have grown up.

Twelve-year-old Bea moves into her grandmother Margaret's apartment in New York while her father waits for heart surgery in the same hospital where her mother died of cancer years earlier. She chafes against his playful antics, insisting she can handle the situation with maturity. One night, Bea goes out to buy a charger for her mother's old camcorder and sees an unfamiliar creature, following it back to her grandmother's building. The next day, she sees the creature again, accompanied by a man. Bea follows them to a nearby house where the man, Cal, retrieves a large furry purple creature named Blue.
