Pine plays a struggling young man who reluctantly returns home for his father's funeral, only to find out a family secret that will change his world - he has a sister and a nephew he never knew existed, and he has no idea how to introduce himself or tell them they're in the will.
"I like the fact that with these characters, it's finally broken down in the end, so in the end, all the armor's off, and what they're dealing with is who the kind of damaged, frail, faulted people that they are, and there's a certain kind of grace in that because I think it's kind of hard to do in real life," Pine said.
Michelle Pfeiffer plays his mom, who is trying to figure out the relationship she has with her son after not seeing him for years.
"Hopefully my son will come home and visit me more often than this character does," Pfeiffer said. "That is yet to be seen, so I don't know."
In the film, Pine's character is trying to learn about his new sister without revealing their connection.
"We don't get to choose our family, but we can certainly choose to love our family," said actress Elizabeth Banks, who plays Pine's sister. "We don't get through life on our own, we need people - we need people like us."
"People Like Us" is rated PG-13.
