A dying wish from their best friend, Anna, compels Cassie, Kate, and Liz, to put old feuds aside and take her seventeen-year-old daughter on an interrailing journey across Europe that they did not quite finish during their studies. Now in their fifties, they are older but not necessarily wiser. With some bad luck, train strikes and romantic entanglements thrown in their way, the trip promises as many laughs and tears and self-discovery as the first time around. The question is: will they reach their destination in time to honour their friends memory?
