Derek and Tyler are identical twins. Tyler is an upstanding young man in love with Jocelyn. Derek is a complete nut case incarcerated in a mental hospital after his reckless driving led to the deaths of a young woman named Maggie and both of his parents.

Tyler pays a well-intentioned visit to the hospital to raise the spirits of his deranged brother, who promptly conks him over the head and switches clothes. While Tyler is unable to convince the medical staff that a switch occurred, Derek assumes Tyler's identity with the goal of taking over where Tyler left off with his girlfriend Jocelyn.

While there was good tension and suspense in the film, there were also some significant lapses. The actor who played both twins was credible in delineating nuances that differentiated the characters of Tyler and Derek. While the audience instantly could tell the twins apart, Tyler's girlfriend Jocelyn was inexplicably blind to the realities of the switch. She should have intuitively recognized that Derek lacked Tyler's sensitivity. His touch would have been different. Even his smell, arriving unshowered from a nut house, should have alerted her to the switch. She absolutely should have recognized that these twins are not necessarily "identical."

There was also a major problem in plotting and continuity after Tyler had failed in multiple escape attempts from the hospital. The lead psychiatrist and the nurses were hopeless in failing to recognize that Tyler's demeanor was different from Derek's. But, suddenly, the psychiatrist and a hospital administrator inform Tyler that they have made a horrible mistake and he is free to leave! There was no explanation or the slightest bit of exposition about how they learned the truth about Derek's escape.

While the performances were excellent, especially the actress playing Jocelyn's over-protective mother Ashley, the ending seemed like a routine meet-up in a cabin with a trigger-happy Derek wielding a rifle he stole from Ashley's neighbor Jake. While out in a shooting range, Jake learned that it was not a good idea to get in front of Derek while he is holding a rifle. And the other characters learned much too late that it is not wise to get in a car when Derek is behind the wheel.

The Twin is not great. First of all, why couldn't they get real twins? It had to have been so annoying having to shoot with the same guy and switch constantly. The writing was not great either. The story was meh and led to a bad buildup. Most Lifetime movies are funny but this was just bland.

This is one of the better Lifetime thrillers. It's actually believable. A concerned mother is worried about her 18 year old daughter and her new boyfriend. Things are moving fast and they want to go an a trip. But little does she know there is a twin and evil twin brother. The evil one had killed their parents in a car crash and then switches place with the good one during a visit. Of course the idiot daughter still won't think there is much wrong after the switch even when the evil one acts more aggressive. It's a little frustrating how long it takes for the good one to prove he is who he is but if it were any faster the story would be over. Anyway the direction is quite swift and things proceed to a satisfying conclusion. Brigid Branagh is the concerned mother. The guy who plays the twins is quite good. Even though they don't have a different hair style or anything you can tell them apart.
