If you mean the part where Christine is underneath the Opera Garnier and she sees the Phantom's face for the first time and he roars in fury, it's called "Beyond the Lake."
If you mean the song at the end where they're singing a seductive song in an opers that the Phantom wrote, and he proposes to her onstage and she rips of his mask and the lynch mob is descending upon him, it's called "The Point of No Return."
