The last time Maggie Campbell and Alexandra Blake worked together, they both received two-week suspensions. This time...it's worse.

Ice begins when a boy is kidnapped from a London park and Detective Inspectors Alex Blake and Maggie Campbell are brought together to work on the case. While their goal is the same, their work ethics are not. Intelligent, perceptive and at times disobedient, Alex Blake does what she believes it takes to do her job. Maggie Campbell has a slightly different approach. She believes that rule books were written for a reason. 

Unexpectedly, their dynamics mesh, but when her feelings for Alex become stronger than she wants to admit, Maggie provokes the worst in Alex to ensure that they will never be partners again. 

Three years later, fate brings them together again. Their assignment is simple, but a plane crash gets in their way. Now, in the middle of a blizzard, they have to try to survive...and fight the feelings that refuse to die.
