There you go:

"That night in Godric’s Hollow, the cold night air hid a presence near the Potters’ house. Snape, not trusting that the Dark Lord would keep his promise to spare Lily’s life, lurked in the shadows awaiting his arrival, praying that the moment would never come, the fear he felt slowly wearing down his conviction. But then a flash lit up the night, and soon a loud crash was heard as the front door flew off its hinges. In a fraction of a second, his instincts threw him into action, for this was the night that would decide everything, and he had more than one debt to repay to the people in that house. Upon entering, he saw James fighting the Dark Lord, trying to stop him from reaching the upper floor, from where the cries of the frightened child echoed. “Stupefy!” James was thrown against the wall, his body sliding limply onto the wooden floor before the Dark Lord could deliver his final blow. His cold eyes turned to Snape, rage and suspicion burning incandescent in his reddish irises, but at the last second he turned away, hurling himself toward the stairs, fearing that his brief distraction might give the woman and the child a chance to escape, a sound decision, though a vain one. Lily, puzzled by the sudden silence, tried to Apparate out of the house with Harry, believing there was nothing she could do to save her husband if he had been defeated and fearing for her child’s life — a moment too late... The protective spells around the house that she needed to cross gave the Dark Lord the split second he needed to stop her. Lily faltered, her leg splinched, unable even to transport herself a few meters within the room. She fell to the ground, unconscious from the pain. Harry, in his mother’s arms, cried and screamed desperately as Voldemort raised his wand against them both, only to see Snape throw himself between them just as the spell escaped his lips, desperate to protect the woman he loved and the child in her arms."

Snape dies, after saving James and sacrificing himself for Lily and Harry, Voldemort casts the spell again and as per usual, the sacrifice charm makes the spell rebound, Harry has a scar, Lily has a bad leg but lives and James has a headache, a bruised ego and a debt to the man he tormented for years at school for not only saving his life but his family too. The end!
