Cathy’s carefree cruise is turned into a tour of duty — complicated by too many beaux.

When her aunt, the ship’s senior nurse, breaks her ankle, Cathy volunteers for duty.

There seems to be more than the usual shipboard intrigue —

The ship’s doctor drinks tea, secretly laced with rum, to forget painful memories.

His young assistant yearns to leave the ship to start his own practice.

A stowaway — on a last fling before settling down to responsibility — is discovered.

A raucous Texas dowager drinks too much and her gigolo-husband has a roving eye.

Cathy herself is faced with an oversupply of admirers.

An innocent flirtation and sudden tragedy make Cathy realize the depth of her dedication to nursing — and where her heart is.
