What would it take to destroy your closest friendship? Alison and Ciara meet at college in Dublin and soon become firm allies, sharing a flat and facing the world together. Ciara is all that Alison aspires to be - sassy, confident and fearless. Although their backgrounds could not be more different, they find solace and humour in each other's company. That is until gorgeous Dan Abernethy, a young medical student, enters their lives, and everything changes irrevocably. Friendship loses out when love turns Alison's world upside down and a terrible betrayal threatens the closeness known only to best friends. It is only when tragedy strikes many years later that Alison and Ciara are able to discover the redemptive power of true friendship.
