Tom and
Jerry, engaged in their typical conflict, notice the baby crawling out of its pram. Their attempts to return the infant are unsuccessful, as it repeatedly escapes. During one such incident, the baby enters
Spike's doghouse. Tom mistakenly grabs Spike instead of the baby, resulting in a violent confrontation. Frustrated, Tom brings the baby back to Jeannie, who misinterprets the situation and hits Tom with a broom. Subsequently, Tom disregards the baby's wanderings. However, when the infant crawls into a 100-story
construction site, Tom and Jerry are compelled to intervene. The baby navigates precariously across steel beams while Tom and Jerry pursue. On the 50th floor, Jerry attempts to save the baby by grasping its
diaper, but the garment detaches. Tom manages to catch the falling infant. In the ensuing confusion, Tom inadvertently dons the diaper himself while the baby crawls away. Believing the baby has entered a cement mixer on the 30th floor, Tom and Jerry dive in, only to discover the infant playing with a
hammer nearby. Later, a panicked Jeannie informs a
police officer about the missing baby. Tom and Jerry return with the infant, exhausted. As Jeannie retrieves the baby, the police officer (voiced by
Bill Thompson) arrests Tom and Jerry under the presumption of kidnapping. In the police car, their explanations are initially dismissed until the baby is seen crawling past, having apparently been neglected by Jeannie once again. This revelation causes the officer to realize Tom and Jerry's innocence. ==Voice cast==
