PLOT:
When viewers first met Richard Castle (Nathan Fillion), a famous mystery novelist and divorced father raising his teenage daughter (Molly Quinn as Alexis), while being kept grounded by his Broadway diva mother (Susan Sullivan as Martha Rodgers), he was creatively blocked. But when the NYPD questioned him in connection with a series of murders staged to imitate crime scenes from his books, Castle found inspiration in the form of Detective Kate Beckett (Stana Katic), a bright and aggressive homicide detective with a fascination for odd and offbeat cases -- a fascination stemming from the years-old unsolved murder of her own mother. Though Castle and Beckett instantly clashed, sparks of another sort also began to fly, leading both to danger and a hint of romance, as Castle stepped in to help find the copycat killer. Once that initial case was solved, the two built on their new relationship, investigating more strange homicides in New York and combining Castle's writer intuition and Beckett's creative detective work. With Beckett as his muse, Castle has used his newfound experience in the field as fodder for his latest and soon-to-be-published bestseller, Heat Wave. But in the season finale, Castle, against Beckett's direct order to stay out of her mom's case, unearthed information about that homicide that may end their relationship forever.

As Season Two begins, Castle is wrestling with how to repair his relationship with Beckett, while struggling to finish Heat Wave. But circumstances force the pair back together to investigate the mysterious murder of a man found dead, tangled in the limbs of a tree. Though their relationship remains rocky, their passion for cracking cases keeps their collaboration cooking. When all is said and done, can Beckett forgive Castle for poking into her past? And can Castle conquer his writer's block long enough to finish his book before its publication deadline?
