Bram Deagan dreams of bringing his family from Ireland to join him in Australia, where he now runs a successful trading business. But when a typhus epidemic strikes Ireland, it leaves the Deagan family decimated. And, with other family members scattered round the world, it is left to Maura Deagan to look after her orphaned nieces and nephew. Forced to abandon her own ambitions, and unsure whether she is ready to become a mother-figure to three young children, Maura recognises that their only hope is to join Bram in far away Australia. So they set sail on the SS Delta, which will carry them there, via the newly opened Suez Canal. It is only when a storm throws her and fellow passenger Hugh Beaufort together that Maura realises this journey may also give her a chance to pursue a dream she set aside long ago - to have a family of her own. That is, until someone from Hugh's past threatens to jeopardise everything . . .
