PC George Garfield is in quite a state - his girlfriend Jenny Delaney has just returned from South America and he is eager to know if she has considered his marriage proposal. Unknown to him, PC Dave Quinnan is also trying to contact Jenny. Both are distracted, but Quinnan nearly blows an obbo to catch a disqualified driver when he tries to call again. As Quinnan makes his excuses and tries to visit Jenny at the nurses' home, he is observed by CID who are staking out St Hugh's Hospital. When Garfield also turns up in a panda car, CID must get him out before their target sees the police car. Finally, Garfield finishes his shift and rushes to the nurses' home in time to see Dave and Jenny kissing at the door.
