Kate has only planned a flying visit to Pennfleet to clear out the family home after the death of her mother. When she finds an anonymous letter, she is drawn back into her own past. Single dad Sam is juggling his deli and two lively teenagers, so romance is the last thing on his mind. Then Cupid fires an unexpected arrow - but what will his children think? Nathan Fisher is happy with his lot, running picnic cruises up and down the river, but kissing the widow of the richest man in Pennfleet has disastrous consequences. Vanessa knows what she has done is unseemly for a widow, but it's the most fun she's had for years. Must she always be on her best behaviour?
