Phrase "Where's my cards?"

[SkiIucK]

I am sitting in my chair, watching this "Michael Clayton" movie and all of a sudden a kid shouts at his mother "Mum, where's my cards?!" Why "is" and not "are"? Is the kid referring to the entire deck which the cards sum up into? Or it's just an improper usage of the language by the kid? Clarify please! Thank you!
Regards,
Mitko

It is common and acceptable in spoken English. First, we are often thinking of the set; second, where's is easier to pronunce than where're.
