Teenaged Susan Turner, with a severe crush on playboy artist Richard Nugent, sneaks into his apartment to model for him and is found there by her sister Judge Margaret Turner. Threatened with jail, Nugent agrees to date Susan until the crush abates. He counters Susan's comic false sophistication by even more comic put-on teenage mannerisms, with a slapstick climax.
Cary Grant is the playboy, Shirley Temple the teenager, and Myrna Loy as her sister. Great film, cast ... and supporting cast.
