It is Christmas in Hammond, Indiana in the 1940's. Nine-year-old boy Ralphie Parker wants a Red Ryder air rifle. His mother tells him that it's not a good idea; he'll shoot his eye out. His teacher, Miss Shields, echoes what his mother said. The department store Santa Claus feels the same way.
On Christmas morning, Ralphie opened all of his presents, but didn't receive the coveted Red Ryder rifle. However, "the Old Man" pointed out that there was one present left unopened. Ralphie tore it open to discover the air rifle.
Ralphie couldn't wait to try out his new toy in the backyard. He placed a target on a metal sign in the backyard and started shooting at it. However, the BB ricochets back at Ralphie and knocks his glasses off. Rendered "blind" in the process, Ralphie really thinks the BB has knocked his eye out and accidentally steps on his glasses, crushing them. Later his mother asks him what happened to his glasses and he makes up a story about an icicle falling off the roof and shattering them. The film ends with Ralphie lying in bed Christmas night, the Red Ryder rifle by his side.
The Christmas Story is based on Jean Shepherd's 1966 novel In God We Trust: All Others Pay Cash. (https://en.wikipedia.org/wiki/In_God_We_Trust:_All_Others_Pay_Cash)
