Time to meet the parents! Or, at least, it's time to have the parents meet. Okay, Martha Rodgers and Jim Beckett met awhile ago, but they’ve never really socialized. That’s why Castle and Beckett set up a dinner with his mom and her dad. Worlds collide! Jim doesn’t think much of flakey actors and Martha doesn’t care for his love of boring baseball. These two have nothing in common. Castle and Beckett are caught in the middle of a total train wreck of an evening. Thankfully, there’s been a murder!

Father Joe McMurtry is gunned down in cold blood in an abandoned building. A local bar owner says a customer named Leo was mouthing off about how he saw someone fleeing a building after gunshots were heard. Ryan is a little uneasy about interviewing a nun. Being a homicide detective is a cakewalk compared to the combat he faced back in Catholic school. The good sister believes a mob enforcer named Mickey Dolan killed the good father. These two polar opposite adults were best friend as kids. Father McMurtry spent a lot of time trying to save his old pal’s soul.

Castle and Beckett are caught off guard when Mickey Dolan’s men sneak up on them at the home of Leo the witness. They lock themselves inside the apartment after the mob thugs snatch up their phones and Beckett’s badge and gun. They hit the streets with Leo to find that Beckett’s car has been stolen. They are stranded in a bad Bronx neighborhood where no one opens their door at night. Beckett breaks into a car to swipe a cell phone. Too bad it’s password-protected and the car alarm gives away their location to the bad guys. Better hide!
